Bin · Konjure

Immutable bytes without an implied text encoding.

Signature

Bin

Cloning shares a packed Arc allocation. bytes constructs Bin from List[u8], Str.utf8 encodes text, and Bin.decode validates UTF-8 with a Res result. Indexing returns Res[u8, DataError]; slicing produces Res[Bin, DataError]. Concatenation creates independent data and respects byte limits.

Methods

len

len() -> f64

Returns the receiver's element, byte, or Unicode scalar count.

decode

decode() -> Res[Str, DataError]

Decodes UTF-8 bytes or returns DataError for malformed input.

get

get(f64) -> Opt[u8]

Returns Some(value) for a valid index and None otherwise.

Examples

Keep bytes distinct from text

Encoding is explicit; byte length and Unicode scalar count differ.
