Struct PresentRanges 

pub struct PresentRanges { /* private fields */ }

The chunk ranges of a hash currently present in the store.

This is the presence oracle the range-aware cache API builds on: read serves only present ranges, resume re-fetches only missing ones, and disk admission accounts present bytes. Absent and logically-evicted hashes report empty + not-complete, matching CacheEngine::has’s eviction masking.

Implementations

impl PresentRanges

pub const fn is_complete(&self) -> bool

The whole blob is present.

pub fn is_empty(&self) -> bool

No range of this hash is present (absent or evicted).

pub const fn chunk_ranges(&self) -> &ChunkRanges

The present ranges, in chunk units.

pub const fn size(&self) -> u64

The blob’s total size in bytes, from the observe() bitfield.

Unlike status(), which iroh-blobs leaves unknown for a partial blob until its LAST chunk validates, the bitfield knows the full size as soon as any chunk carries it (a front-prefix partial with no tail still reports it here). 0 for an absent/evicted/refused hash.
