Implementations

impl MemStore

pub fn new() -> Self

Create a new MemStore

Trait Implementations

impl Clone for MemStore

pub fn clone(&self) -> MemStore

Returns a copy of the value.

impl Default for MemStore

pub fn default() -> MemStore

Returns the "default value" for a type.

impl Store for MemStore

type Ident = Id32

The identifier used for allocations

type Error = MemError

The error the store can emit

pub fn fetch(
    &self,
    id: &Self::Ident,
    into: &mut [u8]
) -> Result<(), Self::Error>

Write bytes associated with Ident

pub fn get<T: Canon<Self>>(&self, id: &Self::Ident) -> Result<T, Self::Error>

pub fn put<T: Canon<Self>>(&self, t: &T) -> Result<Self::Ident, Self::Error>

Encode a value into the store

pub fn put_raw(&self, bytes: &[u8]) -> Result<Self::Ident, Self::Error>

Put raw bytes in store

pub fn ident<T>(t: &T) -> Self::Ident where
    T: Canon<Self>,
