Struct Prefix 

pub struct Prefix {
    pub bytes: Vec<u8>,
    pub offsets: Vec<u64>,
    pub file_len: u64,
}

The header + config + section-table region of a snapshot: everything before the first section body. Small and bounded (kilobytes), so it is materialized even when the bodies stream.

Fields

bytes: Vec<u8>

The prefix bytes, ready to write. The file-hash field is left zero; the caller patches it via SnapshotSink::patch once the whole body has streamed through the running hash.

offsets: Vec<u64>

Absolute byte offset of each section body, in metas order.

file_len: u64

Total file length (aligned end of the last section).

Trait Implementations
