Struct CommitId 

pub struct CommitId(/* private fields */);

Identifies a commit in the history DAG.

A distinct type from BranchId, so the two cannot be swapped; persisted exactly like the u64 it wraps. As an ordered collection key, it uses the same big-endian encoding as u64.

Implementations

impl CommitId

pub const fn from_raw(raw: u64) -> Self

Rebuilds an id from raw (e.g. one persisted by the application). Lookups reject ids that do not exist.

pub const fn raw(self) -> u64

The numeric value, stable across restarts.
