Struct Utf8StreamDecoder 

pub struct Utf8StreamDecoder { /* private fields */ }

An incremental UTF-8 decoder for byte streams.

Network streams (SSE and friends) deliver bytes in arbitrary chunks, so a multi-byte UTF-8 character can be split across two chunks. Decoding each chunk independently with String::from_utf8_lossy corrupts such characters: the truncated head becomes U+FFFD and the continuation bytes in the next chunk become more U+FFFD. This decoder holds back an incomplete trailing sequence until the rest of it arrives.

Genuinely invalid bytes (not a truncated tail) are replaced with U+FFFD, matching lossy semantics.

Implementations

impl Utf8StreamDecoder

pub fn new() -> Utf8StreamDecoder

Create an empty decoder.

pub fn push(&mut self, bytes: &[u8]) -> String

Feed bytes, returning all completely-decodable text.

pub fn flush(&mut self) -> String

Drain any held-back bytes at end of stream (lossy).

Trait Implementations

impl Debug for Utf8StreamDecoder

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

Formats the value using the given formatter.

impl Default for Utf8StreamDecoder

fn default() -> Utf8StreamDecoder

Returns the “default value” for a type.
