Struct PackRangeClaim 

pub struct PackRangeClaim {
    pub pack_id: String,
    pub etag: String,
    pub start: u64,
    pub end: u64,
    /* private fields */
}

One coalesced physical range read, plus the partition of authorized records it covers.

Fields

pack_id: String

etag: String

Provider entity tag pinning the pack revision this claim was resolved against. A repack changes the ETag, invalidating the claim without touching any manifest.

start: u64

end: u64

Implementations

impl PackRangeClaim

pub fn new( pack_id: impl Into<String>, etag: impl Into<String>, start: u64, end: u64, records: Vec<PackRecord>, ) -> PackRangeClaim

Build a claim over records, sorting them into offset-canonical order.

Sorting here is deliberate and is the whole point of weft #1070: the canonical order is physical, so a pack whose object order differs from its offset order still produces a contiguous, checkable partition.

pub fn records(&self) -> &[PackRecord]

Records in offset-canonical order.

pub fn byte_len(&self) -> Option<u64>

Total bytes this claim authorizes, or None if the range is inverted.

pub fn encode(&self) -> Vec<u8>

Encode to the single canonical byte string for this claim.

pub fn address(&self) -> ContentHash

The claim’s content address — BLAKE3 of its canonical bytes.

pub fn decode(bytes: &[u8]) -> Result<PackRangeClaim, PackClaimDecodeError>

Decode strictly, rejecting truncation, trailing bytes, non-UTF-8 ids, out-of-order records, and any non-canonical spelling.
