Struct CompressedFrame 

pub struct CompressedFrame { /* private fields */ }

A delta-encoded frame snapshot.

Stores only the cells that changed from the previous frame. The first frame in a recording is always a full snapshot (all non-empty cells are stored as changes from an empty buffer).

Implementations

impl CompressedFrame

pub fn full(buf: &Buffer) -> Self

Create a full snapshot (delta from empty buffer).

pub fn delta(current: &Buffer, previous: &Buffer) -> Self

Create a delta-encoded snapshot from the previous buffer state.

pub fn apply_to(&self, buf: &mut Buffer)

Apply this frame’s changes to a buffer.

The buffer must have matching dimensions.

pub fn change_count(&self) -> usize

Number of changed cells in this frame.

pub fn memory_size(&self) -> usize

Estimated memory size in bytes.

pub fn with_cursor(self, cursor: Option<(u16, u16)>) -> Self

Set cursor position for this frame.

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

Performs copy-assignment from source.

impl Debug for CompressedFrame

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