Struct TileDependencyGraph 

pub struct TileDependencyGraph {
    pub edges: Vec<TileDependency>,
    pub cols: u32,
    pub rows: u32,
}

Dependency graph for a tile layout.

Fields

edges: Vec<TileDependency>

All dependency edges.

cols: u32

Number of tile columns.

rows: u32

Number of tile rows.

Implementations

impl TileDependencyGraph

pub fn build(layout: &TileLayout) -> Self

Build a dependency graph for the given layout.

By default, each tile depends on its left neighbour (entropy context) and its top neighbour (loop filter boundary). The caller can add motion-vector dependencies afterwards.

pub fn add_mv_dependency(&mut self, from: (u32, u32), to: (u32, u32))

Add a motion-vector dependency between two tiles.

pub fn dependencies_of(&self, col: u32, row: u32) -> Vec<&TileDependency>

Return all tiles that (col, row) depends on.

pub fn ready_tiles(&self, encoded: &[(u32, u32)]) -> Vec<(u32, u32)>

Return tiles that can be encoded independently (no incoming dependencies from tiles that haven’t been encoded yet).

encoded is a set of already-encoded tile coordinates.

Trait Implementations

impl Clone for TileDependencyGraph

fn clone(&self) -> TileDependencyGraph

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TileDependencyGraph

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

Formats the value using the given formatter.
