Struct rustfmt_nightly::config::file_lines::FileLines

pub struct FileLines(_);

A set of lines in files.

It is represented as a multimap keyed on file names, with values a collection of non-overlapping ranges sorted by their start point. An inner None is interpreted to mean all lines in all files.

Methods

impl FileLines

pub fn all() -> FileLines

Creates a FileLines that contains all lines in all files.

pub fn is_all(&self) -> bool

Returns true if this FileLines contains all lines in all files.

pub fn from_ranges(ranges: HashMap<FileName, Vec<Range>>) -> FileLines

Important traits for Files<'a>

impl<'a> Iterator for Files<'a> type Item = &'a FileName;

pub fn files(&self) -> Files

Returns an iterator over the files contained in self.

pub fn contains(&self, range: &LineRange) -> bool

Returns true if range is fully contained in self.

pub fn intersects(&self, range: &LineRange) -> bool

Returns true if any lines in range are in self.

pub fn contains_line(&self, file_name: &FileName, line: usize) -> bool

Returns true if line from file_name is in self.

pub fn intersects_range(
    &self,
    file_name: &FileName,
    lo: usize,
    hi: usize
) -> bool

Returns true if any of the lines between lo and hi from file_name are in self.
