Crate atomo

Atomo is an atomic execution engine for Rust. At its core it is a database wrapper that enhances any backend storage engine with an optimized snapshot functionality.

Structs

Atomo

Atomo is the concurrent query and update execution engine that can allow many queries to run in parallel while a single update thread takes ownership of mutating the states.

AtomoBuilder

The builder API to use for opening an Atomo database.

BincodeSerde

The bincode serializer from the bincode crate.

KeyIterator

An iterator over the keys of the table.

OncePtr

An atomic pointer that can only be initialized once.

QueryPerm

The query permission on an Atomo only allows non-mutating changes.

ResolvedTableReference

A resolved table reference can be used to cache the lookup of a table by its string name and the type validations and can be used to speed up the TableSelector::get_table function.

TableRef

A reference to a table inside an execution context (i.e TableSelector). A table reference can be used as a reference to a table to operate on it.

TableSelector

The table selector contain multiple tables and is provided to the user at the beginning of a query or an update. You can think about this as the execution context.

UpdatePerm

The update permission on an Atomo which allows mutating the data.

Traits

SerdeBackend

The serialization backend that can empower [Atomo] with Serde for serializing the data for the persistence layer.
