Struct DirSet

pub struct DirSet {
    pub dirs: Vec<Dir>,
}

Represents a set of root directories, supporting overlay and override semantics. Later directories in the set can override files from earlier ones with the same relative path.

Fields

dirs: Vec<Dir>

The list of root directories, in order of increasing precedence.

Implementations

impl DirSet

pub fn new(dirs: Vec<Dir>) -> Self

Creates a new DirSet from the given list of directories. The order of directories determines override precedence.

pub fn get_file(&self, name: &str) -> Option<File>

Returns the file with the given name, searching roots in reverse order. Files in later roots override those in earlier roots if the relative path matches.

pub fn get_dir(&self, name: &str) -> Option<Dir>

pub fn walk(&self) -> impl Iterator<Item = File>

Recursively walks all files in all root directories. Files with the same relative path from different roots are all included.

pub fn walk_override(&self) -> impl Iterator<Item = File>

Recursively walks all files, yielding only the highest-precedence file for each relative path. This implements the override behaviour: later roots take precedence over earlier ones.

Trait Implementations

impl Clone for DirSet

fn clone(&self) -> DirSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DirSet

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

Formats the value using the given formatter.

impl Hash for DirSet

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DirSet

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