pub enum DataError {
    TypeMismatch,
    InvalidLiteral,
    InvalidUtf8,
    Overflow,
    NonFinite,
    InexactConversion,
    DivisionByZero,

    Bounds,

}

Failure to construct, index, convert, or evaluate typed data.

Variants

TypeMismatch

An operation requires operands with the same declared element type.

InvalidLiteral

Text is not a valid literal of the requested type.

InvalidUtf8

Bytes are not valid UTF-8 where a text value is required.

Overflow

A value or checked integer operation exceeds the destination range.

NonFinite

Infinity and NaN cannot enter a portable data value.

InexactConversion

A conversion would round, truncate, or discard a signed zero.

DivisionByZero

Division or remainder has a zero divisor.

InvalidShape

Shape, rank, or buffer length is not a valid tensor layout.

ShapeMismatch

Shapes cannot participate in the requested operation.

Bounds

An index is outside the requested value.

InvalidSlice

Slice selectors are malformed, including a zero step.

InvalidMetadata

Decoded media metadata disagrees with its payload.

AllocationLimit

A checked allocation exceeds the portable data limit.

Implementations

impl DataError

pub const VARIANTS: &[DataErrorDescriptor]

Every data error with its stable name and documentation.

pub const fn name(self) -> &'static str

Stable variant name used by generated host and language bindings.

Trait Implementations

impl Clone for DataError

fn clone(&self) -> DataError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for DataError

impl Debug for DataError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DataError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DataError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for DataError

impl Error for DataError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for DataError

fn eq(&self, other: &DataError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DataError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
