}

Text encoding, mirroring espeak_ng_ENCODING from encoding.h.

Variants are in the same order as the C enum so that casting a raw integer (e.g. from a binary data file) to Encoding works correctly.

Use Encoding::from_name to resolve an IANA/MIME name, and TextDecoder to decode byte streams.

Variants

Unknown = 0

Iso8859_1 = 2

UTF-8 Unicode.

Ucs2 = 20

UCS-2 little-endian (16-bit Unicode, no surrogates).

Implementations

impl Encoding

pub fn from_name(name: &str) -> Self

Resolve an encoding from its IANA/MIME name.

Mirrors espeak_ng_EncodingFromName() in encoding.c, which uses the mnem_encoding[] table. Comparison is case-insensitive.

pub fn is_single_byte(self) -> bool

Returns true if this is a single-byte encoding (includes ASCII).

pub fn codepage(self) -> Option<&'static [u16; 128]>

Return the codepage table for single-byte encodings, if one exists. The table maps bytes 0x80–0xFF (index = byte - 0x80) to Unicode codepoints.

Trait Implementations

impl Clone for Encoding

fn clone(&self) -> Encoding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Encoding

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

Formats the value using the given formatter.

impl Hash for Encoding

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 Encoding

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