Struct TileCache 

pub struct TileCache { /* private fields */ }

Multi-level tile cache

Implementations

impl TileCache

pub fn new(config: TileCacheConfig) -> Self

Create a new tile cache

pub fn get(&self, key: &CacheKey) -> Option<Bytes>

Get a tile from the cache

pub fn put(&self, key: CacheKey, data: Bytes) -> CacheResult<()>

Put a tile in the cache

pub fn clear(&self) -> CacheResult<()>

Clear all cached entries

If an internal lock is poisoned (a prior panic occurred while it was held), the poisoned guard is recovered via into_inner() so the clear still takes effect, and the poisoning is surfaced via a warning rather than silently leaving stale state behind.

pub fn stats(&self) -> CacheStats

Get cache statistics

On lock poisoning, the last-known stats are recovered (they remain valid after a panic) and a warning is emitted, instead of silently returning a zeroed default that would hide the underlying fault from operators.

Trait Implementations

impl Clone for TileCache

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
