Struct Latin1Codec 

pub struct Latin1Codec;

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

Latin1Codec converts between ISO-8859-1 bytes and Unicode scalar values.

Implementations

impl Latin1Codec

pub const fn charset(self) -> Charset

Returns the ISO-8859-1 charset descriptor.

Returns

Returns Charset::ISO_8859_1.

pub const fn max_units_per_char(self) -> usize

Returns the maximum number of bytes needed for one Latin-1 character.

Returns

Returns 1.

Trait Implementations

impl CharsetCodec for Latin1Codec

fn charset(&self) -> Charset

Returns the charset descriptor for this codec.

Returns

Returns Charset::ISO_8859_1.

fn max_units_per_char(&self) -> usize

Returns the maximum number of output bytes for one character.

Returns

Returns 1.

fn decode_one( &self, input: &[u8], index: usize, ) -> CharsetDecodeResult<DecodeStatus>

Decodes one ISO-8859-1 byte into a char.

Parameters

• input: Complete input byte slice.
• index: Absolute byte index at which decoding starts.

Returns

Ok(DecodeStatus::Complete { value, consumed: 1 }) always when input exists.

Errors

Returns CharsetDecodeErrorKind::MalformedSequence when index is out of range.

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

Encodes one char into one ISO-8859-1 byte.

Parameters

• ch: The character to encode.
• output: Output byte slice.
• index: Absolute output index where writing starts.

Returns

Ok(1) when one byte is written.

Errors

• CharsetEncodeErrorKind::BufferTooSmall if index >= output.len().
• CharsetEncodeErrorKind::UnmappableCharacter if ch > U+00FF.

type Unit = u8

Storage unit used by the encoded representation.

impl Clone for Latin1Codec

fn clone(&self) -> Latin1Codec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Latin1Codec

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

Formats the value using the given formatter.

impl Default for Latin1Codec

fn default() -> Latin1Codec

Returns the “default value” for a type.

impl Hash for Latin1Codec

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 Latin1Codec

fn eq(&self, other: &Latin1Codec) -> 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.
