Crate qubit_codec_text 

Qubit Text Codec

Low-level Unicode constants, character classification helpers, and text codec primitives for ASCII, ISO-8859-1, UTF-8, UTF-16, and UTF-32-oriented code.

This crate deliberately stays below std::io::Read and std::io::Write. Concrete text I/O adapters are expected to own buffering, EOF handling, line endings, and std::io::Error mapping while using the codecs from this crate for strict buffer-level encoding and decoding.

Modules

prelude

Common imports for Qubit Text Codec callers.

Structs

AsciiCodec

Single-byte ASCII codec for bytes.

Charset

Identifies the charset associated with a codec or error.

CharsetConverter

Converts units encoded with one charset into units encoded with another charset.

CharsetDecodeError

Error reported by a charset decoder.

CharsetDecodePolicy

Malformed-input policy used by charset decoders and converters.

CharsetDecoder

Converts units of one charset into Unicode scalar values.

CharsetEncodeError

Error reported by a charset encoder.

CharsetEncodePolicy

Unmappable-input policy used by charset encoders and converters.

CharsetEncoder

Converts Unicode scalar values into units of one charset.

Latin1Codec

Single-byte ISO-8859-1 codec for bytes.

TranscodeProgress

Counts how much work a crate::BufferedTranscoder completed before returning.

Error reported while converting between two charsets.

CharsetDecodeErrorKind

Classifies failures detected while decoding encoded units into Unicode text.

CharsetEncodeErrorKind

Classifies failures detected while encoding Unicode text into encoded units.

MalformedAction

Policy used when input units do not form a valid character.

TranscodeStatus

Reports why a crate::BufferedTranscoder stopped converting input.

Unicode

Namespace for Unicode constants and encoding-independent code point helpers.

Charset metadata carried by a low-level Codec<Value = char>.

CharsetEncodeProbe

Encoding-size probe used by crate::CharsetEncoder.

Codec

Encodes and decodes one value or codec quantum against a unit buffer.

Type Aliases

Result type returned by charset decoders.

CharsetEncodeResult

Result type returned by charset encoders.
