Enum TrieCacheContext

Source

pub enum TrieCacheContext {
    Trusted,
    Untrusted,
}

Expand description

Specify the desired trie cache context when calling Backend::state_at.

This is used to determine the size of the local trie cache.

Variants§

§

Trusted

This is used when calling Backend::state_at in a trusted context.

A trusted context is for example the building or importing of a block. In this case the local trie cache can grow unlimited and all the cached data will be propagated back to the shared trie cache. It is safe to let the local cache grow to hold the entire data, because importing and building blocks is bounded by the block size limit.

§

Untrusted

This is used when calling Backend::state_at in from untrusted context.

The local trie cache will be bounded by its preconfigured size.
