Expand description

Generator-wide store of boundary corner columns, keyed by cell column.

Fields§

§shards: Box<[SyncMutex<Shard>]>

Implementations§

Source §

impl CornerColumnStore

Source

fn shard(&self, key: (i32, i32)) -> &SyncMutex<Shard>

Source

pub fn consume(&self, key: (i32, i32), read: impl FnOnce(&[f32])) -> bool

read a shared column and count this chunk’s use; false on a miss

Source

pub fn produce( &self, key: (i32, i32), users: u8, values: impl FnOnce() -> Box<[f32]>, )

keep a column for the other chunk a race just counts this chunk use
