Enum TrieCacheMode 

pub enum TrieCacheMode {
    CachingShard,
    CachingChunk,
}

Mode of the trie cache.

Variants

CachingShard

In this mode we put each visited node to LRU cache to optimize performance. Presence of any exact node is not guaranteed.

CachingChunk

In this mode we put each visited node to the chunk cache which is a hash map. This is needed to guarantee that all nodes for which we charged a touching trie node cost are retrieved from DB only once during a single chunk processing. Such nodes remain in cache until the chunk processing is finished, and thus users (potentially different) are not required to pay twice for retrieval of the same node.

Trait Implementations

impl Clone for TrieCacheMode

fn clone(&self) -> TrieCacheMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TrieCacheMode

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

Formats the value using the given formatter.

impl PartialEq for TrieCacheMode

fn eq(&self, other: &TrieCacheMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
