Module bundle 

The caller-facing half of asset negotiation: a bag of key → bytes that knows how to hash itself.

Nobody using this crate should ever compute a sha256 or hand-build an AssetManifest — that is the whole point. Fill an AssetBundle with the same flat AssetProvider keys mdcast uses everywhere else (img/logo.png, typst/layouts/pdf/hero.typ, reference/reference.docx), hand it to a render call, and the digests, the manifest, and the upload of whatever the server is missing all follow from it.

Structs

AssetBundle

Asset key → bytes (or a digest with bytes fetched lazily), for one render.

Functions

sha256

The sha256 of bytes, in the form the wire protocol names blobs by.

Type Aliases

BlobFetchError

The error a digest-only entry’s fetch closure failed with. Opaque on purpose — the caller’s storage layer (a DB, a filesystem, an object store) is not this crate’s concern, only that the failure is reported rather than swallowed.
