Struct Tile 

pub struct Tile {
    pub key: TileKey,
    pub pixels: Vec<u8>,
    pub coverage: Vec<u8>,
    pub provisional: Vec<u8>,
    pub quality: Vec<u8>,
    pub conflicts: Vec<u8>,
    pub owner: Vec<u32>,
    pub score: Vec<f32>,
    pub frozen: Vec<u8>,
    pub dirty: bool,
    pub existed: bool,
    pub touched: Option<f64>,
    /* private fields */
}

One resident tile: RGBA pixels and the side planes kept per pixel (coverage, provisional) and per 16×16 block (quality, conflicts, owner frame + 1, score, frozen).

Fields

key: TileKey

pixels: Vec<u8>

coverage: Vec<u8>

provisional: Vec<u8>

quality: Vec<u8>

conflicts: Vec<u8>

owner: Vec<u32>

score: Vec<f32>

frozen: Vec<u8>

dirty: bool

Written since it was last stored.

existed: bool

Has a stored copy (it was loaded from one, or stored since).

touched: Option<f64>

The host’s timestamp of the last write that dirtied it; None reads as 0.

Implementations

impl Tile

pub fn id(&self) -> u32

Stable while the tile stays resident; a reloaded tile gets a new one.

pub fn observed(&self) -> u64

Covered pixels, the observed field of the tile’s tile-index/ row.

Trait Implementations

impl Clone for Tile

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tile

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

Formats the value using the given formatter.

impl PartialEq for Tile

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
