Struct StreamingValidator 

pub struct StreamingValidator { /* private fields */ }

Streaming UTF-8 validator for fragmented text frames.

WebSocket spec §6.2 may split text frames into multiple DATA frames (FIN=0) — the UTF-8 stream may be interrupted in the middle of a multi-byte sequence. This validator maintains a small internal buffer for the codepoint that has been started.

Implementations

impl StreamingValidator

pub fn new() -> Self

Constructor.

pub fn feed(&mut self, chunk: &[u8]) -> Result<(), Utf8Error>

Check a chunk of bytes. Returns Ok(()) if (together with the previous state) everything so far is valid.

Errors

See Utf8Error.

pub fn finalize(self) -> Result<(), Utf8Error>

true if the stream ends on a codepoint boundary (no pending byte). A text frame with FIN=1 MUST reach this state — otherwise a truncated error.

Errors

Utf8Error::Truncated if pending bytes remain.

impl Debug for StreamingValidator

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

impl Default for StreamingValidator

fn default() -> StreamingValidator
