Enum GitCommitHash 

pub enum GitCommitHash {
    Sha1([u8; 20]),
    Sha256([u8; 32]),
}

A Git commit hash.

This type guarantees the contained value is either:

• 20 bytes (SHA-1, displayed as 40 lowercase hex characters)
• 32 bytes (SHA-256, displayed as 64 lowercase hex characters)

Parsing

Parse from a hex string using FromStr:

use git_stub::GitCommitHash;

let hash: GitCommitHash =
    "0123456789abcdef0123456789abcdef01234567".parse().unwrap();

Variants

Sha1([u8; 20])

A SHA-1 hash: the one traditionally used in Git.

Sha256([u8; 32])

A SHA-256 hash, supported by newer versions of Git.

Trait Implementations

impl Clone for GitCommitHash

fn clone(&self) -> GitCommitHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GitCommitHash

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

Formats the value using the given formatter.

impl Display for GitCommitHash

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

Formats the value using the given formatter.

impl FromStr for GitCommitHash

type Err = CommitHashParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for GitCommitHash

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

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 GitCommitHash

fn cmp(&self, other: &GitCommitHash) -> 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.

impl PartialEq for GitCommitHash

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for GitCommitHash

fn partial_cmp(&self, other: &GitCommitHash) -> 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.
