Struct PreimageApplied 

pub struct PreimageApplied { /* private fields */ }

Outcome of a LaneState::advance_preimage fold.

Both deltas are zero for a reveal that advanced nothing — one at or below the tracked frontier, or one naming a superseded epoch. Neither is an error: a duplicate or out-of-order reveal is ordinary under concurrent streams, and the node answers it by continuing to deliver, exactly as for an already-satisfied voucher.

Implementations

impl PreimageApplied

pub const ZERO: Self

The reveal advanced nothing. Two cases reach it and callers treat them identically, because the answer is the same in both: the reveal was at or below the tracked frontier (already covered, and nothing was hashed to find that out), or it named an epoch the lane no longer tracks (real, but superseded by a signature that folded a frontier at least as deep).

pub const fn amount_delta(&self) -> U256

Amount this reveal added to the lane’s claim.

pub const fn bytes_delta(&self) -> U256

Bytes this reveal’s steps paid for.

pub fn advanced(&self) -> bool

true when the reveal advanced the lane’s claim.
