Struct HeadTailBuffer 

pub struct HeadTailBuffer { /* private fields */ }

Byte buffer that preserves the beginning and end, dropping the middle.

Implementations

impl HeadTailBuffer

pub fn new(max_bytes: usize) -> Self

pub fn push_chunk(&mut self, chunk: Vec<u8>)

pub fn snapshot(&self) -> Vec<Vec<u8>>

pub fn to_bytes(&self) -> Vec<u8>

pub fn to_bytes_with_omission_marker(&self, marker: &[u8]) -> Vec<u8>

pub fn suffix_bytes(&self, max_bytes: usize) -> Vec<u8>

Return up to max_bytes from the end of the retained content (head followed by tail), preserving order. Avoids allocating the full buffer when only a suffix is needed.

pub fn drain(&mut self) -> Vec<Vec<u8>>

pub fn drain_into(&mut self, target: &mut HeadTailBuffer)

pub fn retained_bytes(&self) -> usize

pub fn omitted_bytes(&self) -> usize

pub fn head_bytes(&self) -> usize

Length in bytes of the retained head (the split point: to_bytes() is the head followed by the tail, with omitted_bytes dropped between).
