Struct S3BlobStore 

pub struct S3BlobStore { /* private fields */ }

An immutable object backend. All operations reuse the supplied SDK client.

Implementations

impl S3BlobStore

pub fn new(client: Client, options: S3BlobStoreOptions) -> Result<Self>

Validate local options without accessing credentials or making requests. The supplied client may target AWS S3 or a compatible endpoint supporting conditional writes. SDK diagnostics are deliberately not included in errors.

Trait Implementations

impl Clone for S3BlobStore

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for S3BlobStore

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

Formats the value using the given formatter.

impl ImmutableBlobStore for S3BlobStore

fn kind(&self) -> &'static str

Stable, non-secret provider identifier used to isolate manifest paths.

fn max_blob_size(&self) -> usize

Maximum encoded blob size, including the certificate wire envelope.

fn create<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 str, value: &'life2 [u8], ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

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

Create only when absent; return false if already present.

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

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

Read an immutable object; only confirmed absence returns None.

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,

Check object presence. The default uses the same bounded read path.
