Trait (interface) of decoder

Required methods

fn to_string_lossless(&self, input: &[u8]) -> Option<String>

Converts to UTF-8 String only if possible completely

Arguments

• input - sequence of bytes that may represent a string

fn to_string_lossy(&self, input: &[u8]) -> String

Converts to UTF-8 String by force (filling with replacement characters)

Arguments

• input - sequence of bytes that may represent a string

fn encoding_name(&self) -> &str

Returns the name of the encoding that the decoder uses

Provided methods

fn can_decode(&self, input: &[u8]) -> bool

Returns true if input is valid sequence for encoding

Arguments

• input - sequence of bytes that may represent a string

Implementations
