Struct git2::Oid [−][src]
pub struct Oid { /* fields omitted */ }
Unique identity of any object (commit, tree, blob, tag).
Methods
impl Oid
[src]
impl Oid
pub fn from_str(s: &str) -> Result<Oid, Error>
[src]
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.
pub fn from_bytes(bytes: &[u8]) -> Result<Oid, Error>
[src]
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.
pub fn zero() -> Oid
[src]
pub fn zero() -> Oid
Creates an all zero Oid structure.
pub fn hash_object(kind: ObjectType, bytes: &[u8]) -> Result<Oid, Error>
[src]
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.
pub fn hash_file<P: AsRef<Path>>(
kind: ObjectType,
path: P
) -> Result<Oid, Error>
[src]
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.
pub fn as_bytes(&self) -> &[u8]
[src]
pub fn as_bytes(&self) -> &[u8]
View this OID as a byte-slice 20 bytes in length.
pub fn is_zero(&self) -> bool
[src]
pub fn is_zero(&self) -> bool
Test if this OID is all zeros.
