Struct InheritedStepProgress 

pub struct InheritedStepProgress { /* private fields */ }

Committed step progress one chunk-step attempt inherits.

A restart resumes bounded policy limits and stable retry-key identity from the durable state its attempt inherited, so a retry budget is not refilled by restarting the process.

Implementations

impl InheritedStepProgress

pub const NONE: Self

The progress a standalone or first-attempt chunk step inherits.

pub const fn new( read_ordinal: u64, checkpoint_digest: [u8; 32], fault: FaultProgress, ) -> Self

Constructs inherited progress from durable step state.

pub const fn read_ordinal(self) -> u64

Returns the stable reader ordinal the next chunk continues from.

pub const fn checkpoint_digest(self) -> [u8; 32]

Returns the digest of the last committed checkpoint.

Retry keys are derived from this generation, so an inherited digest makes a reserved ordinal resumable after restart.

pub const fn fault(self) -> FaultProgress

Returns the inherited committed fault-tolerance totals.
