Struct Rewrites

pub struct Rewrites {
    pub copies: Option<Copies>,
    pub percentage: Option<f32>,
    pub limit: usize,
}

Available on crate feature blob only.

A structure to capture how to perform rename and copy tracking, used by the rewrites::Tracker.

Fields

copies: Option<Copies>

If Some(…), also find copies. None is the default which does not try to detect copies at all.

Note that this is an even more expensive operation than detecting renames stemming from additions and deletions as the resulting set to search through is usually larger.

percentage: Option<f32>

The percentage of similarity needed for files to be considered renamed, defaulting to Some(0.5). This field is similar to git diff -M50%.

If None, files are only considered equal if their content matches 100%. Note that values greater than 1.0 have no different effect than 1.0.

limit: usize

The amount of files to consider for fuzzy rename or copy tracking. Defaults to 1000, meaning that only 1000*1000 combinations can be tested for fuzzy matches, i.e. the ones that try to find matches by comparing similarity. If 0, there is no limit.

If the limit would not be enough to test the entire set of combinations, the algorithm will trade in precision and not run the fuzzy version of identity tests at all. That way results are never partial.

Trait Implementations

impl Clone for Rewrites

fn clone(&self) -> Rewrites

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rewrites

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

Formats the value using the given formatter.

impl Default for Rewrites

The default settings for rewrites according to the git configuration defaults.

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Rewrites

fn eq(&self, other: &Rewrites) -> 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.
