Struct ConvHistory 

pub struct ConvHistory { /* private fields */ }

Zero-allocation flat ring buffer storing recent convolution state snapshots for speculative decoding rollback.

Implementations

impl ConvHistory

pub fn new(buf_len: usize) -> Self

Create a new pre-allocated history ring buffer for a convolution layer with buf_len elements.

pub fn push(&mut self, pos: usize, buffer: &[f32])

Record a snapshot of buffer at sequence position pos. Zero heap allocation: copies into the pre-allocated flat storage.

pub fn rollback_to(&mut self, target_pos: usize, buffer: &mut [f32]) -> bool

Roll back the convolution buffer to the state at target_pos. Returns true if the state was successfully found and restored.

pub fn has_pos(&self, target_pos: usize) -> bool

Check whether a snapshot at target_pos is available in this ring buffer.

pub fn clear(&mut self)

Reset all snapshot tracking without deallocating.

Trait Implementations

impl Clone for ConvHistory

fn clone(&self) -> ConvHistory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConvHistory

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

Formats the value using the given formatter.
