Enum jj_lib::fileset::FilesetExpression

pub enum FilesetExpression {
    None,
    All,
    Pattern(FilePattern),
    UnionAll(Vec<FilesetExpression>),
    Intersection(Box<FilesetExpression>, Box<FilesetExpression>),
    Difference(Box<FilesetExpression>, Box<FilesetExpression>),
}

AST-level representation of the fileset expression.

Variants

None

Matches nothing.

All

Matches everything.

Pattern(FilePattern)

Matches basic pattern.

UnionAll(Vec<FilesetExpression>)

Matches any of the expressions.

Use FilesetExpression::union_all() to construct a union expression. It will normalize 0-ary or 1-ary union.

Intersection(Box<FilesetExpression>, Box<FilesetExpression>)

Matches both expressions.

Difference(Box<FilesetExpression>, Box<FilesetExpression>)

Matches the first expression, but not the second expression.

Implementations

impl FilesetExpression

pub fn none() -> Self

Expression that matches nothing.

pub fn all() -> Self

Expression that matches everything.

pub fn pattern(pattern: FilePattern) -> Self

Expression that matches the given pattern.

pub fn file_path(path: RepoPathBuf) -> Self

Expression that matches file (or exact) path.

pub fn prefix_path(path: RepoPathBuf) -> Self

Expression that matches path prefix.

pub fn union_all(expressions: Vec<FilesetExpression>) -> Self

Expression that matches any of the given expressions.

pub fn intersection(self, other: Self) -> Self

Expression that matches both self and other.

pub fn difference(self, other: Self) -> Self

Expression that matches self but not other.

pub fn explicit_paths(&self) -> impl Iterator<Item = &RepoPath>

Iterates literal paths recursively from this expression.

For example, "a", "b", "c" will be yielded in that order for expression "a" | all() & "b" | ~"c".

pub fn to_matcher(&self) -> Box<dyn Matcher>

Transforms the expression tree to Matcher object.

Trait Implementations

impl Clone for FilesetExpression

fn clone(&self) -> FilesetExpression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FilesetExpression

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

Formats the value using the given formatter.

impl PartialEq for FilesetExpression

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