Struct InMemoryStorage 

pub struct InMemoryStorage { /* private fields */ }

An in-memory StorageBackend for testing packagers and recorders without touching the filesystem. Cheap to clone (shared object map).

Implementations

impl InMemoryStorage

pub fn new() -> Self

A new, empty store.

pub fn len(&self) -> usize

Number of stored objects.

pub fn is_empty(&self) -> bool

Whether the store is empty.

Trait Implementations

impl Clone for InMemoryStorage

fn clone(&self) -> InMemoryStorage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for InMemoryStorage

fn default() -> InMemoryStorage

Returns the “default value” for a type.

impl StorageBackend for InMemoryStorage

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

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

Write data at key. Overwrites if the key exists.

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

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

Read the object stored at key.

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

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

Delete the object at key.

fn list<'life0, 'life1, 'async_trait>( &'life0 self, prefix: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>>> + Send + 'async_trait>>

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

List all keys with the given prefix.

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

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

Returns true if the object exists.

fn put_file<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 str, path: &'life2 Path, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Write the file at path to key, then remove the source file.
