Enum BlobBody 

pub enum BlobBody {
    Cached(Bytes),
    Mapped(Bytes),
    Stream(GetObject),
}

A blob body to serve: a cached, in-memory buffer (small hot assets) or a streaming handle straight from storage (everything else).

Variants

Cached(Bytes)

A small blob served from the in-memory cache as one refcounted frame.

Mapped(Bytes)

A large blob served as one borrowed frame backed by a memory-mapped local file — no tokio::fs double-buffer copy, and a single content-length body instead of a chunked stream. Only local-file backends produce this.

Stream(GetObject)

A blob streamed from storage (too large to cache, or Range/large path).
