#[non_exhaustive]pub enum VerifiedReader {
Cached {
data: Bytes,
pos: usize,
},
Live(LiveReader),
}Expand description
An AsyncRead over a blob’s verified contiguous front, clamped to the
verified frontier by construction (it only reads bytes the engine has already
bao-verified). Its cursor paces the paired StreamDrive.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Cached
A whole-blob cache hit: served straight from memory, no fetch.
Live(LiveReader)
A live fetch: the reader waits for the drive to verify bytes into the fill store and hands out the verified prefix.
