Struct ObjectId 

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

Content address of a snapshot object: SHA-256 of [kind][payload].

Displays and parses as lowercase hex. A CommitId is the same type, named for the role it plays as the root pointer a host persists.

Implementations

impl ObjectId

pub fn as_bytes(&self) -> &[u8; 32]

Raw 32-byte digest.

pub fn from_bytes(bytes: [u8; 32]) -> Self

Build from a raw 32-byte digest.

pub fn to_hex(self) -> String

Lowercase hex form.

pub fn from_hex(s: &str) -> Result<Self>

Parse from lowercase or uppercase hex.

Decodes byte pairs directly rather than slicing the str. Object ids arrive from callers in three languages, and s.len() counts bytes: a 64-byte string holding any multi-byte character would otherwise be sliced mid-character and panic instead of returning an error.

Trait Implementations
