Struct DepNodeColorMap

pub(super) struct DepNodeColorMap {
    values: IndexVec<SerializedDepNodeIndex, AtomicU32>,
}

Fields§

§values: IndexVec<SerializedDepNodeIndex, AtomicU32>

Implementations§

Source§

impl DepNodeColorMap

Source

fn new(size: usize) -> DepNodeColorMap

Source

pub(super) fn current( &self, index: SerializedDepNodeIndex, ) -> Option<DepNodeIndex>

Source

pub(super) fn try_mark( &self, prev_index: SerializedDepNodeIndex, index: DepNodeIndex, green: bool, ) -> Result<(), Option<DepNodeIndex>>

This tries to atomically mark a node green and assign index as the new index if green is true, otherwise it will try to atomicaly mark it red.

This returns Ok if index gets assigned or the node is marked red, otherwise it returns the already allocated index in Err if it is green already. If it was already red, Err(None) is returned.

Source

pub(super) fn get(&self, index: SerializedDepNodeIndex) -> DepNodeColor

Source

pub(super) fn insert_red(&self, index: SerializedDepNodeIndex)
