Struct OriginRangeRequest 

pub struct OriginRangeRequest {
    pub fetch_start: u64,
    pub fetch_end: u64,
}

The chunk-group-aligned span a Origin::fetch_range_data call must fetch, passed from the engine to the adapter. This is the produced-by-engine half of the range pull; the verify-against-root half lives in crate::range_pull and crate::origin_range.

Fields

fetch_start: u64

First byte of the chunk-group-aligned data span to fetch (inclusive).

fetch_end: u64

One past the last byte of the data span to fetch (exclusive). The adapter issues an inclusive-end Range/GetObject read of [fetch_start, fetch_end).

Implementations

impl OriginRangeRequest

pub const fn len(&self) -> u64

Number of data bytes to fetch (fetch_end - fetch_start). Saturating so a mis-constructed request can never underflow; the engine always builds these from a validated crate::range_pull::AlignedRange, where fetch_end >= fetch_start holds by construction.

pub const fn is_empty(&self) -> bool

Is the requested span empty? Only true for a zero-length blob; the engine never issues an empty range against a non-empty blob.
