Implementations

impl LayoutCache

pub fn new() -> Self

pub fn generation(&self) -> u64

Returns the current generation counter.

pub fn invalidate(&mut self)

Bump the generation counter, logically invalidating all cached entries without eagerly clearing them. Subsequent lookups with the old generation will miss until re-populated.

pub fn is_valid(&self, key: LayoutKey, current_gen: u64) -> bool

Check whether a cached entry for the given key is still valid against the current generation.

pub fn clear(&mut self)

pub fn get_size(&self, view_hash: u64, proposal: SizeProposal) -> Option<Size>

pub fn set_size(&mut self, view_hash: u64, proposal: SizeProposal, size: Size)

pub fn invalidate_view(&mut self, view_hash: u64)

Remove all cached size entries for a specific view hash.

Trait Implementations

impl Default for LayoutCache
