Enum bip_metainfo::PieceAccess

pub enum PieceAccess<'a> {
    Compute(&'a mut Read),
    PreComputed(ShaHash),
}

Type of access given for computing (or not) the checksums for torrent files.

Implementations should typically choose to invoke the access_pieces callback with all Compute variants, or all PreComputed variants. It is allowable to mix and match variants between calls, but any PreComputed hashes will be considered as the next checksum to be put in the torrent file, so implementations will typically want to align calls with Compute to a piece length boundary (though not required).

Variants

Compute(&'a mut Read)

Hash should be computed from the bytes read.

PreComputed(ShaHash)

Hash given should be used directly as the next checksum.
