Enum BackwardCommit 

pub enum BackwardCommit {
    Format {
        reason: &'static str,
    },
    Layout {
        offset: u64,
        length: u64,
    },
}

Outcome of validating the candidate preamble at the offset produced by parse_backward_postamble.

Variants

Format

Format error during preamble validation. Caller disables the backward walker and discards any provisional suffix layouts (matching Rust’s disable_backward).

Fields

reason: &'static str

Stable identifier; one of the REASON_*_BWD / REASON_PREAMBLE_POSTAMBLE_LENGTH_MISMATCH / REASON_STREAMING_PREAMBLE_NON_TAIL constants.

Layout

Preamble validated. The caller’s commit-decision step inspects this against the forward outcome to detect overlap, same-message meet, or a clean backward record.

Fields

offset: u64

Confirmed message-start offset.

length: u64

Confirmed message length (bytes).

Trait Implementations

impl Clone for BackwardCommit

fn clone(&self) -> BackwardCommit

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for BackwardCommit

impl Debug for BackwardCommit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for BackwardCommit

impl PartialEq for BackwardCommit

fn eq(&self, other: &BackwardCommit) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BackwardCommit

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
