Struct git_attributes::PatternList

pub struct PatternList<T: Pattern> {
    pub patterns: Vec<PatternMapping<T::Value>>,
    pub source: Option<PathBuf>,
    pub base: Option<BString>,
}

A list of patterns which optionally know where they were loaded from and what their base is.

Knowing their base which is relative to a source directory, it will ignore all path to match against that don’t also start with said base.

Fields

patterns: Vec<PatternMapping<T::Value>>

Patterns and their associated data in the order they were loaded in or specified, the line number in its source file or its sequence number ((pattern, value, line_number)).

During matching, this order is reversed.

source: Option<PathBuf>

The path from which the patterns were read, or None if the patterns don’t originate in a file on disk.

base: Option<BString>

The parent directory of source, or None if the patterns are global to match against the repository root. It’s processed to contain slashes only and to end with a trailing slash, and is relative to the repository root.

Implementations

impl<T> PatternList<T> where
    T: Pattern, 

pub fn from_bytes(
    bytes: &[u8],
    source: impl Into<PathBuf>,
    root: Option<&Path>
) -> Self

source is the location of the bytes which represent a list of patterns line by line.

pub fn from_file(
    source: impl Into<PathBuf>,
    root: Option<&Path>,
    follow_symlinks: bool,
    buf: &mut Vec<u8>
) -> Result<Option<Self>>

Create a pattern list from the source file, which may be located underneath root, while optionally following symlinks with follow_symlinks, providing buf to temporarily store the data contained in the file.

impl<T> PatternList<T> where
    T: Pattern, 

pub fn pattern_matching_relative_path(
    &self,
    relative_path: &BStr,
    basename_pos: Option<usize>,
    is_dir: Option<bool>,
    case: Case
) -> Option<Match<'_, T::Value>>

Return a match if a pattern matches relative_path, providing a pre-computed basename_pos which is the starting position of the basename of relative_path. is_dir is true if relative_path is a directory. case specifies whether cases should be folded during matching or not.

pub fn pattern_idx_matching_relative_path(
    &self,
    relative_path: &BStr,
    basename_pos: Option<usize>,
    is_dir: Option<bool>,
    case: Case
) -> Option<usize>

Like pattern_matching_relative_path(), but returns an index to the pattern that matched relative_path, instead of the match itself.

impl PatternList<Ignore>

pub fn from_overrides(
    patterns: impl IntoIterator<Item = impl Into<OsString>>
) -> Self

Parse a list of patterns, using slashes as path separators

Trait Implementations

impl<T: Clone + Pattern> Clone for PatternList<T> where
    T::Value: Clone, 

fn clone(&self) -> PatternList<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Pattern> Debug for PatternList<T> where
    T::Value: Debug, 

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

Formats the value using the given formatter.

impl<T: Default + Pattern> Default for PatternList<T> where
    T::Value: Default, 

fn default() -> PatternList<T>

Returns the “default value” for a type.

impl<T: Hash + Pattern> Hash for PatternList<T> where
    T::Value: Hash, 

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, 

Feeds a slice of this type into the given Hasher.

impl<T: Ord + Pattern> Ord for PatternList<T> where
    T::Value: Ord, 

fn cmp(&self, other: &PatternList<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self where
    Self: PartialOrd<Self>, 

Restrict a value to a certain interval.

impl<T: PartialEq + Pattern> PartialEq<PatternList<T>> for PatternList<T> where
    T::Value: PartialEq, 

fn eq(&self, other: &PatternList<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: PartialOrd + Pattern> PartialOrd<PatternList<T>> for PatternList<T> where
    T::Value: PartialOrd, 

fn partial_cmp(&self, other: &PatternList<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
