Enum PrefixHint

pub enum PrefixHint<'a> {
    MustBeCommit,
    DescribeAnchor {
        ref_name: &'a BStr,
        generation: usize,
    },
}

A hint to make disambiguation when looking up prefixes possible.

Variants

MustBeCommit

The prefix must be a commit.

DescribeAnchor

The prefix refers to a commit, anchored to a ref and a revision generation in its future.

Fields

ref_name: &'a BStr

The name of the reference, like v1.2.3 or main.

generation: usize

The future generation of the commit we look for, with 0 meaning the commit is referenced by ref_name directly.

Trait Implementations

impl<'a> Clone for PrefixHint<'a>

fn clone(&self) -> PrefixHint<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for PrefixHint<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for PrefixHint<'a>

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<'a> Ord for PrefixHint<'a>

fn cmp(&self, other: &PrefixHint<'a>) -> 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<'a> PartialEq for PrefixHint<'a>

fn eq(&self, other: &PrefixHint<'a>) -> 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<'a> PartialOrd for PrefixHint<'a>

fn partial_cmp(&self, other: &PrefixHint<'a>) -> 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.
