pub struct LiveRuntime { /* private fields */ }Expand description
An explicitly stepped language runtime with a bounded, replayable journal.
Implementations§
Source§impl LiveRuntime
impl LiveRuntime
Sourcepub fn new() -> Self
pub fn new() -> Self
Creates an empty session. The first accepted command must be LiveCommand::Load.
Sourcepub fn apply(&mut self, command: LiveCommand) -> Result<LiveEvent, LiveError>
pub fn apply(&mut self, command: LiveCommand) -> Result<LiveEvent, LiveError>
Applies a command transactionally and appends its exact event to the journal.
§Errors
Rejects oversized inputs, invalid runtime actions, or a full journal without changing the accepted runtime, sequence, or history.
Sourcepub fn accept(&mut self, event: LiveEvent) -> Result<(), LiveError>
pub fn accept(&mut self, event: LiveEvent) -> Result<(), LiveError>
Accepts one replay event only when its sequence is exactly next.
§Errors
Rejects gaps, duplicates, and invalid commands without changing this session.
Sourcepub fn restore(&mut self, history: LiveHistory) -> Result<(), LiveError>
pub fn restore(&mut self, history: LiveHistory) -> Result<(), LiveError>
Replays a complete retained history transactionally, then replaces this session.
§Errors
Rejects non-contiguous, oversized, or invalid histories while preserving state.
Sourcepub fn snapshot(&self) -> Option<Snapshot>
pub fn snapshot(&self) -> Option<Snapshot>
Returns the accepted language state, if a revision has loaded.
Sourcepub fn execution_state(&self) -> Option<(u64, bool)>
pub fn execution_state(&self) -> Option<(u64, bool)>
Returns the accepted runtime tick and terminal lifecycle state without cloning the scene or snapshot.
Sourcepub fn render(&self) -> Result<RenderOutput, LiveError>
pub fn render(&self) -> Result<RenderOutput, LiveError>
Returns validated generated render data for the accepted language state.
Sourcepub fn history(&self) -> &LiveHistory
pub fn history(&self) -> &LiveHistory
Returns the bounded retained journal suffix.
Sourcepub const fn sequence(&self) -> u64
pub const fn sequence(&self) -> u64
Returns the last globally assigned session sequence number.
Sourcepub const fn source_revision(&self) -> u64
pub const fn source_revision(&self) -> u64
Returns the sequence of the last accepted source load.
Simulation ticks and invocations do not change this revision, so it can safely be used as an optimistic-concurrency precondition for source edits.
Sourcepub fn edit_source(
&mut self,
base_revision: u64,
source: ProgramSource,
) -> Result<LiveEvent, LiveError>
pub fn edit_source( &mut self, base_revision: u64, source: ProgramSource, ) -> Result<LiveEvent, LiveError>
Compiles and accepts a complete source replacement at one exact base revision.
§Errors
Rejects stale or invalid candidates without changing the accepted runtime, journal, source revision, or playback state owned by the host.
Source§impl LiveRuntime
impl LiveRuntime
Sourcepub fn ui_document(&self) -> Result<UiDocument, LiveError>
pub fn ui_document(&self) -> Result<UiDocument, LiveError>
Returns source-revision-bound controls for this accepted session.
Sourcepub fn ui_command(&self, event: &UiEvent) -> Result<LiveCommand, LiveError>
pub fn ui_command(&self, event: &UiEvent) -> Result<LiveCommand, LiveError>
Validates a displayed control and resolves its Rust-owned callback command.
The relay orders the returned command through Self::apply.

§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();§fn bright_black(&self) -> Painted<&T>

§fn bg(&self, value: Color) -> Painted<&T>

Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling [Attribute] value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();§fn rapid_blink(&self) -> Painted<&T>

§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi [Quirk] value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the [Condition] value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);§impl<SS, SP> SupersetOf<SS> for SPwhere
