Struct KeyedDirs 

pub struct KeyedDirs { /* private fields */ }

The keyed directories of a policy.

Implementations

impl KeyedDirs

pub fn new<'a>( entries: impl IntoIterator<Item = (&'a str, &'a str, Compare)>, ) -> Result<Self, String>

Compiles (directory, pattern, compare). Refused: more than MAX_DIRS, a directory that is no plain relative path, a pattern longer than MAX_PATTERN, that does not compile within the size limit, or that has other than exactly one capture group.

pub fn is_empty(&self) -> bool

pub fn get(&self, dir: &str) -> Option<&KeyedDir>

The keyed directory dir.

pub fn of<'p>(&self, path: &'p str) -> Option<(&KeyedDir, &'p str)>

The keyed directory that holds path directly, and the file’s name. A file in a directory under it is not one of its files.

pub fn clashes<'p>( &self, paths: impl IntoIterator<Item = &'p str>, ) -> BTreeSet<String>

The keys, as dir#key, that two or more of paths have in one keyed directory.

pub fn taken<'p>( &self, added: &[String], tree: impl IntoIterator<Item = &'p str> + Clone, ) -> Vec<String>

The keys, as dir#key, of the files in added that another file of tree (the paths of the tree they are in) has too.

pub fn next_key<'p>( &self, dir: &str, tree: impl IntoIterator<Item = &'p str>, reserved: impl IntoIterator<Item = &'p str>, ) -> Option<String>

The number after the highest key that a file of tree has in dir or that reserved holds; 1 when there is none. None for a text directory, whose keys have no order, or one that is not keyed.
