Struct Location 

pub struct Location<Name> {
    pub descendant: Name,
    pub distance: u64,
}

The position of one node in the graph relative their known descendant. This structure is relevant when the IdMap is lazy. Assuming that all parents of merges and all heads are known then any node can be represented as their first descendant and the distance to that descendant.

Example: 0 - a - b - c In this example our initial commit is 0, then we have a the first commit, b second, c third. { descendant: c, distance: 1, } => [b]

Fields

descendant: Name

distance: u64

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Name: Debug> Debug for Location<Name>

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

Formats the value using the given formatter.

impl<Name: Default> Default for Location<Name>

fn default() -> Location<Name>

Returns the “default value” for a type.

impl<'de, Name> Deserialize<'de> for Location<Name>

where Name: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Name: Hash> Hash for Location<Name>

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,

impl<Name: Ord> Ord for Location<Name>

fn cmp(&self, other: &Location<Name>) -> 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<Name: PartialEq> PartialEq for Location<Name>

fn eq(&self, other: &Location<Name>) -> 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.

fn partial_cmp(&self, other: &Location<Name>) -> 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.

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.
