Struct CopyHistory

pub struct CopyHistory {
    pub current_path: RepoPathBuf,
    pub parents: Vec<CopyId>,
    pub salt: Vec<u8>,
}

Describes the copy history of a file. The copy object is unchanged when a file is modified.

Fields

current_path: RepoPathBuf

The file’s current path.

parents: Vec<CopyId>

IDs of the files that became the current incarnation of this file.

A newly created file has no parents. A regular copy or rename has one parent. A merge of multiple files has multiple parents.

salt: Vec<u8>

An optional piece of data to give the Copy object a different ID. May be randomly generated. This allows a commit to say that a file was replaced by a new incarnation of it, indicating a logically distinct file taking the place of the previous file at the path.

Trait Implementations

impl Clone for CopyHistory

fn clone(&self) -> CopyHistory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ContentHash for CopyHistory

fn hash(&self, state: &mut impl Update)

Update the hasher state with this object’s content

impl Debug for CopyHistory

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

Formats the value using the given formatter.

impl Ord for CopyHistory

fn cmp(&self, other: &CopyHistory) -> 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 CopyHistory

fn eq(&self, other: &CopyHistory) -> 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 CopyHistory

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