Enum StreamOutcome 

pub enum StreamOutcome {
    Complete {
        version: Version,
    },
    Corrupt {
        reached: Option<Version>,
    },
    Mismatch {
        reached: Option<Version>,
        got: Version,
    },
}

How one stream’s import ended, and where the stream sits afterward.

“Where it sits” lives inside each variant so the success case always carries a real Version while the trouble cases carry Option (None = the stream was never touched). Illegal states (a “complete” stream with no version) are unrepresentable.

Variants

Complete

Every block offered for this stream was applied; it is now at version.

Fields

version: Version

Corrupt

A block failed its per-block checksum. The good prefix (if any) was applied, leaving the stream at reached (None = untouched). The corrupt block’s own version is deliberately absent — a failed checksum means its decoded header cannot be trusted; re-fetch from reached’s successor.

Fields

reached: Option<Version>

Mismatch

A block’s version did not match the stream’s next expected version (stale overlap or forward gap). Good prefix applied, stream left at reached; got is trustworthy (the checksum passed, only the position was wrong).

Fields

reached: Option<Version>

got: Version

Implementations

impl StreamOutcome

pub const fn is_complete(&self) -> bool

pub const fn reached(&self) -> Option<Version>
