Enum KeyCache 

pub enum KeyCache {
    Disabled,
    Shared(Arc<Mutex<LruCache<PublicKey, ()>>>),
}

A cache for public keys.

This is used solely to make parsing public keys from byte slices more efficient for the very common case where a large number of identical keys are being parsed, like in the relay server.

The cache stores only successful parse results.

Variants

Disabled

The key cache is disabled.

Shared(Arc<Mutex<LruCache<PublicKey, ()>>>)

The key cache is enabled with a fixed capacity. It is shared between multiple threads.

Implementations

impl KeyCache

pub fn new(capacity: usize) -> Self

Create a new key cache with the given capacity.

If the capacity is zero, the cache is disabled and has zero overhead.

pub fn key_from_slice( &self, slice: &[u8], ) -> Result<PublicKey, <PublicKey as TryFrom<&'static [u8]>>::Error>

Get a key from a slice of bytes.

Trait Implementations

impl Clone for KeyCache

fn clone(&self) -> KeyCache

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyCache

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
