Struct GitOid 

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

Git object id, 40 lowercase hex digits (SHA-1 repositories; other lengths are rejected; SHA-256 repositories are not accepted).

Implementations

impl GitOid

pub fn from_bytes(bytes: [u8; 20]) -> GitOid

pub fn parse(raw: &str) -> Option<GitOid>

The hex spelling, read back.

Public because a checkpoint identity travels as a string in more than one direction: the wire deserialises one, and a client that was shown a checkpoint in a sentence has to turn it back into an oid to act on it. Without this the caller decodes its own hex, which is a second definition of what an oid looks like - the exact thing the note on Deserialize below says stays here.

None on anything that is not exactly forty lowercase hex digits: a wrong length is a refusal, never a padded guess.

Trait Implementations

impl Clone for GitOid

fn clone(&self) -> GitOid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GitOid

impl Debug for GitOid

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GitOid

fn deserialize<D>( deserializer: D, ) -> Result<GitOid, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

The shape authority stays here, so the wire (wire::frames) has no second definition of what an oid looks like.

impl Display for GitOid

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

Formats the value using the given formatter.

impl Eq for GitOid

impl Hash for GitOid

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for GitOid

fn cmp(&self, other: &GitOid) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for GitOid

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for GitOid

fn partial_cmp(&self, other: &GitOid) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for GitOid

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
