Implementations§

source§

impl Oid

source

pub fn from_str(s: &str) -> Result<Oid, Error>

Parse a hex-formatted object id into an Oid structure.

§Errors

Returns an error if the string is empty, is longer than 40 hex characters, or contains any non-hex characters.

source

pub fn from_bytes(bytes: &[u8]) -> Result<Oid, Error>

Parse a raw object id into an Oid structure.

If the array given is not 20 bytes in length, an error is returned.

source

pub fn zero() -> Oid

Creates an all zero Oid structure.

source

pub fn hash_object(kind: ObjectType, bytes: &[u8]) -> Result<Oid, Error>

Hashes the provided data as an object of the provided type, and returns an Oid corresponding to the result. This does not store the object inside any object database or repository.

source

pub fn hash_file<P: AsRef<Path>>( kind: ObjectType, path: P ) -> Result<Oid, Error>

Hashes the content of the provided file as an object of the provided type, and returns an Oid corresponding to the result. This does not store the object inside any object database or repository.

source

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

View this OID as a byte-slice 20 bytes in length.

source

pub fn is_zero(&self) -> bool

Test if this OID is all zeros.
