Struct MemorySource 

pub struct MemorySource { /* private fields */ }

A simple in-memory source useful for testing and embedded environments.

Implementations

impl MemorySource

pub fn new() -> Self

Creates a new empty MemorySource.

pub fn insert(&mut self, key: &str, value: Vec<u8>)

Inserts data into the source.

Trait Implementations

impl Default for MemorySource

fn default() -> MemorySource

Returns the “default value” for a type.

impl Source for MemorySource

fn read<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, FmtError>> + Send + 'async_trait>>

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

Read raw data as a vector of bytes.

fn exists<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

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

Check if the resource exists at the given key.
