Struct Config 

pub struct Config<T: Translator, J, S: Strategy, B = ()> {
    pub merkle_config: Config<S>,
    pub journal_config: J,
    pub grafted_metadata_partition: String,
    pub translator: T,
    pub init_cache: Option<NonZeroUsize>,
    pub init_buffer: NonZeroUsize,
    pub init_concurrency: B,
}

Configuration for a Current authenticated db.

Fields

merkle_config: Config<S>

Configuration for the Merkle structure backing the authenticated journal.

journal_config: J

Configuration for the operations log journal.

grafted_metadata_partition: String

The name of the storage partition used for grafted tree metadata.

translator: T

The translator used by the compressed index. Ordered databases require an OrderedTranslator.

init_cache: Option<NonZeroUsize>

Maximum number of entries in the (location -> key) cache used during init to resolve snapshot collisions without re-reading the log; None disables it.

init_buffer: NonZeroUsize

Size (in bytes) of the read buffer used to replay the log during init.

init_concurrency: B

The index’s snapshot-build concurrency (see crate::qmdb::SnapshotBuild::Concurrency): () for index types that build serially, and the number of build tasks for index types that build in parallel. A value of 1 builds the index entirely on the init task. Values of 2 and 3 decode on the init task and insert on one or two workers. Larger values split between spawned decode and insert tasks while the init task merely forwards batches.

Trait Implementations

impl<T: Clone + Translator, J: Clone, S: Clone + Strategy, B: Clone> Clone for Config<T, J, S, B>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Translator, J, S: Strategy, B> From<Config<T, J, S, B>> for Config<T, J, S, B>

fn from(cfg: Config<T, J, S, B>) -> Self

Converts to this type from the input type.
