pub trait PackCache {
// Required methods
fn get(&mut self, key: Key) -> Result<Option<&[u8]>>;
fn put(&mut self, key: Key, pack: &[u8]) -> Result<()>;
}Expand description
Hosts own persistence, eviction and concurrency. A failed insertion must
preserve the old entry. Successful insertion publishes complete immutable
bytes atomically. Returned bytes are always verified by write before use.
Required Methods§
fn get(&mut self, key: Key) -> Result<Option<&[u8]>>
fn put(&mut self, key: Key, pack: &[u8]) -> Result<()>
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
