Trait SegmentSource 

pub trait SegmentSource:
    'static
    + Send
    + Sync {
    // Required method
    fn request(&self, id: SegmentId) -> SegmentFuture;
}

Provides segment data to a crate::LayoutReader.

Implementations may issue asynchronous file reads, object-store requests, cache lookups, or in-memory buffer slices. Returned futures must be independent and safe to poll concurrently.

Required Methods

fn request(&self, id: SegmentId) -> SegmentFuture

Request a segment, returning a future that will eventually resolve to the segment data.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
