Struct gix::Pathspec

pub struct Pathspec<'repo> { /* private fields */ }

Available on crate feature attributes only.

A utility to make matching against pathspecs simple.

Note that to perform pathspec matching, attribute access might need to be provided. For that, we use our own and argue that the implementation is only going to incur costs for it when a pathspec matches and has attributes. Should this potential duplication of effort to maintain attribute state be unacceptable, the user may fall back to the underlying plumbing.

Implementations

impl<'repo> Pathspec<'repo>

Lifecycle

pub fn new( repo: &'repo Repository, patterns: impl IntoIterator<Item = impl AsRef<BStr>>, inherit_ignore_case: bool, make_attributes: impl FnOnce() -> Result<Stack, Box<dyn Error + Send + Sync + 'static>> ) -> Result<Self, Error>

Create a new instance by parsing patterns into Pathspecs to make them usable for searches. make_attribute may be called if one of the patterns has a (attr:a) element which requires attribute matching. It should be used to control where attributes are coming from. If inherit_ignore_case is true, the pathspecs may have their ignore-case default overridden to be case-insensitive by default. This only works towards turning ignore-case for pathspecs on, but won’t ever turn that setting off if.

Deviation

Pathspecs can declare to be case-insensitive as part of their elements, which is a setting that is now respected for attribute queries as well.

pub fn into_parts(self) -> (Search, Option<AttributeStack<'repo>>)

Turn ourselves into the functional parts for direct usage. Note that the cache is only set if one of the search patterns is specifying attributes to match for.

pub fn detach(self) -> Result<PathspecDetached>

Turn ourselves into an implementation that works without a repository instance and that is rather minimal.

impl<'repo> Pathspec<'repo>

Access

pub fn attributes(&self) -> Option<&Stack>

Return the attributes cache which is used when matching attributes in pathspecs, or None if none of the pathspecs require that.

pub fn search(&self) -> &Search

Return the search itself which can be used for matching paths or accessing the actual patterns that will be used.

pub fn pattern_matching_relative_path<'a>( &mut self, relative_path: impl Into<&'a BStr>, is_dir: Option<bool> ) -> Option<Match<'_>>

Return the first Match of relative_path, or None. Note that the match might be excluded. is_dir is true if relative_path is a directory.

pub fn is_included<'a>( &mut self, relative_path: impl Into<&'a BStr>, is_dir: Option<bool> ) -> bool

The simplified version of pattern_matching_relative_path() which returns true if relative_path is included in the set of positive pathspecs, while not being excluded.

pub fn index_entries_with_paths<'s: 'repo, 'a: 'repo>( &'s mut self, index: &'a State ) -> Option<impl Iterator<Item = (&'a BStr, &'a Entry)> + 'repo + 's>

Return an iterator over all entries along with their path if the path matches the pathspec, or None if the pathspec is known to match no entry.

Trait Implementations

impl<'repo> Clone for Pathspec<'repo>

fn clone(&self) -> Pathspec<'repo>

Returns a copy of the value.

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

Performs copy-assignment from source.
