Struct pest::inputs::FileInput

pub struct FileInput { /* fields omitted */ }

A struct useful for matching Files by allocating the contents at the beginning.

Methods

impl FileInput

fn new<P: AsRef<Path>>(path: P) -> Result<FileInput>

Creates a new FileInput from a File.

Examples

let input = FileInput::new("file").unwrap();

Trait Implementations

impl Debug for FileInput

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Input for FileInput

fn len(&self) -> usize

Returns length of the input.

fn is_empty(&self) -> bool

Returns whether the input is empty.

fn file_name(&self) -> Option<OsString>

Returns the file name of the input or None in the case where it doesn't have one.

unsafe fn slice(&self, start: usize, end: usize) -> &str

Slices the input.

unsafe fn line_col(&self, pos: usize) -> (usize, usize)

Returns the line - and column number of the input at pos.

unsafe fn line_of(&self, pos: usize) -> &str

Returns the line of the input at pos.

unsafe fn skip(&self, n: usize, pos: usize) -> Option<usize>

Tries to skip n chars at pos. Returns Some(len) with the UTF-8 length of the skipped chars position or None if there are not enough chars left to skip.

unsafe fn match_string(&self, string: &str, pos: usize) -> bool

Matches string at pos and returns whether it matched.

unsafe fn match_insensitive(&self, string: &str, pos: usize) -> bool

Matches string at pos case insensitively and returns whether it matched.

unsafe fn match_range(&self, range: Range<char>, pos: usize) -> Option<usize>

Matches if the char is within the range and returns Some(len) with the matching char's UTF-8 length if it matched or None otherwise.
