Struct S3SlideSource 

pub struct S3SlideSource { /* private fields */ }

S3-backed implementation of SlideSource.

Creates S3RangeReader instances for slides stored in an S3 bucket. The slide ID is used as the object key within the bucket.

Example

use wsi_streamer::slide::S3SlideSource;
use wsi_streamer::io::create_s3_client;

let client = create_s3_client(None).await;
let source = S3SlideSource::new(client, "my-bucket".to_string());

// The slide ID "slides/example.svs" becomes the S3 key
let reader = source.create_reader("slides/example.svs").await?;

Implementations

impl S3SlideSource

pub fn new(client: Client, bucket: String) -> Self

Create a new S3SlideSource for the given bucket.

Arguments

• client - AWS S3 client to use for requests
• bucket - S3 bucket name containing the slides

pub fn bucket(&self) -> &str

Get the bucket name.

Trait Implementations

impl Clone for S3SlideSource

fn clone(&self) -> S3SlideSource

Returns a duplicate of the value.

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

impl SlideSource for S3SlideSource

type Reader = S3RangeReader

The type of range reader this source creates.

fn create_reader<'life0, 'life1, 'async_trait>( &'life0 self, slide_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Self::Reader, IoError>> + Send + 'async_trait>>

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

Create a range reader for the given slide identifier.

fn list_slides<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, limit: u32, cursor: Option<&'life1 str>, prefix: Option<&'life2 str>, ) -> Pin<Box<dyn Future<Output = Result<SlideListResult, IoError>> + Send + 'async_trait>>

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

List available slides from the storage backend.
