The behaviour needed by the reader interface.

Required methods

fn next_char(&mut self, bookmarks: &mut BookmarkManager) -> Result<char, Error>

Read the next character from input.

fn advance_char(&mut self, bookmarks: &mut BookmarkManager)

Advance along the input without returning the character.

fn character(&self) -> Char<Error>

Get the current character from the reader.

fn finished(&self, bookmarks: &BookmarkManager) -> bool

Check if the reader has finished reading.

A reader is finished when it has no further input left to read, and when it does not need to rewind to any point.

fn empty(&self) -> bool

Check if the reader is empty.

fn fill(&mut self, bookmarks: &mut BookmarkManager)

Fill the buffer with words from the input.

fn max_possible_rewind_len(&self, bookmarks: &BookmarkManager) -> usize

Get the maximum possible rewind for the reader.

fn append_result(&mut self, char: char)

Append the provided character to the reader’s result.

fn pop_result(&mut self) -> String

Return self.result and sets the internal result to empty.

fn offset(&self) -> usize

Get the reader’s current offset in the buffer.

fn result(&self) -> &String

Get an immutable reference to the reader’s result.

fn result_mut(&mut self) -> &mut String

Get a mutable reference to the reader’s result.

fn buffer_len(&self) -> usize

Get the current length of the reader’s buffer.

fn set_offset(&mut self, off: usize)

Set the buffer offset to the specified value.

fn truncate_match(&mut self, len: usize)

Truncate the current match to the provided length.
