Struct MemoryBlob 

pub struct MemoryBlob { /* private fields */ }

An in-memory cratefield_core::Blob store for module tests: keeps objects in a map, and has no presigned URLs (so signed_url reports Unsupported, as a directory store does).

Implementations

impl MemoryBlob

pub fn new() -> Self

pub fn len(&self) -> usize

How many objects are stored, for assertions.

pub fn is_empty(&self) -> bool

Whether the store is empty, for assertions.

Trait Implementations

impl Blob for MemoryBlob

fn put<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, key: &'life1 str, bytes: &'life2 [u8], content_type: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<(), BlobError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Stores bytes at key with content_type, replacing any existing object.

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

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

Fetches the object at key, or None if there is none.

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

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

Removes the object at key. Idempotent: removing a missing key is Ok.

fn signed_url<'life0, 'life1, 'async_trait>( &'life0 self, _key: &'life1 str, _ttl: Duration, ) -> Pin<Box<dyn Future<Output = Result<String, BlobError>> + Send + 'async_trait>>

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

A URL that serves the object directly for ttl, skipping the Worker. Adapters without presigned URLs (a directory store) return BlobError::Unsupported; callers then serve the bytes through get.

impl Clone for MemoryBlob

fn clone(&self) -> MemoryBlob

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for MemoryBlob

fn default() -> MemoryBlob

Returns the “default value” for a type.
