Struct AsciiCodec 

pub struct AsciiCodec;

Single-byte ASCII codec for bytes.

AsciiCodec converts between one-byte ASCII-encoded data and Unicode scalar values.

Implementations

impl AsciiCodec

pub const fn charset(self) -> Charset

Returns the ASCII charset descriptor.

Returns

Returns Charset::ASCII.

Trait Implementations

impl CharsetCodec for AsciiCodec

fn charset(&self) -> Charset

Returns the charset descriptor for this codec.

Returns

Returns Charset::ASCII.

impl CharsetEncodeProbe for AsciiCodec

fn encode_len(&self, ch: char, index: usize) -> CharsetEncodeResult<usize>

Encodes one char into one ASCII byte.

Parameters

• ch: The character to encode.
• index: Input character index used for error context.

Returns

Ok(1) when one byte is needed.

Errors

• CharsetEncodeErrorKind::UnmappableCharacter if ch is not ASCII.

impl Clone for AsciiCodec

fn clone(&self) -> AsciiCodec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Codec for AsciiCodec

type Value = char

Logical value decoded from or encoded into the buffer.

type Unit = u8

Buffer unit used by the encoded representation.

type DecodeError = CharsetDecodeError

Error reported when decoding malformed units.

type EncodeError = CharsetEncodeError

Error reported when encoding an unsupported value.

fn min_units_per_value(&self) -> NonZeroUsize

Returns the minimum possible unit count for one encoded value.

fn max_units_per_value(&self) -> NonZeroUsize

Returns the maximum non-zero unit count needed to encode or decode one value.

unsafe fn decode_unchecked( &self, input: &[u8], index: usize, ) -> CharsetDecodeResult<(char, NonZeroUsize)>

Decodes one value from input starting at index.

unsafe fn encode_unchecked( &self, ch: &char, output: &mut [u8], index: usize, ) -> CharsetEncodeResult<usize>

Encodes one borrowed value into output starting at index.

impl Copy for AsciiCodec

impl Debug for AsciiCodec

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

Formats the value using the given formatter.

impl Default for AsciiCodec

fn default() -> AsciiCodec

Returns the “default value” for a type.

impl Eq for AsciiCodec

impl Hash for AsciiCodec

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AsciiCodec

fn eq(&self, other: &AsciiCodec) -> 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.
