Struct webrender::gpu_cache::BlockIndex

struct BlockIndex(NonZeroU32);

Represents the index of a Block in the block array. We only create such structs for blocks that represent the start of a chunk.

Because we use Option in a lot of places, we use a NonZeroU32 here and avoid ever using the index zero.

Tuple Fields

0: NonZeroU32

Formats the value using the given formatter.

impl MallocSizeOf for BlockIndex

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize
