Struct MemoryStore 

pub struct MemoryStore { /* private fields */ }

A store that keeps everything in memory.

What the M3 milestone runs on, and a first-class part of the crate for the same reason the mock reasoner is: a test, a cassette replay, and a policy check all want a store that needs no filesystem.

Implementations

impl MemoryStore

pub fn new() -> Self

An empty store.

pub fn len(&self) -> usize

How many distinct blobs are held.

Distinct, not written: content addressing means storing the same bytes twice stores them once, and this is how that is asserted.

pub fn is_empty(&self) -> bool

Whether nothing has been stored.

Trait Implementations

impl Debug for MemoryStore

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

Formats the value using the given formatter.

impl Default for MemoryStore

fn default() -> Self

Returns the “default value” for a type.

impl Store for MemoryStore

fn put<'life0, 'life1, 'async_trait>( &'life0 self, bytes: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Result<Digest, StoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Write bytes, returning their content address.

fn get<'life0, 'life1, 'async_trait>( &'life0 self, digest: &'life1 Digest, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, StoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Read bytes back by address.
