Required methods

fn iter(&self) -> Box<dyn DoubleEndedIterator<Item = (usize, char)>>

Obtain an iterator over the characters within the source file, together with their respective byte positions.

fn iter_from(
    &self,
    offset: usize
) -> Box<dyn DoubleEndedIterator<Item = (usize, char)>>

Obtain an iterator over the characters within the source file, starting at the provided location offset, together with their respective byte positions.

fn extract(&self, begin: usize, end: usize) -> String

Copy a range of the source content into a String instance owned by the caller, possibly converting the encoding such that the result is in UTF-8.

fn extract_iter(
    &self,
    begin: usize,
    end: usize
) -> Box<dyn DoubleEndedIterator<Item = (usize, char)>>

Obtain an iterator over an extract of the source content. This might be more efficient than copying the extract into a String.

fn bytes(&self) -> &[u8]

Obtain a slice voer all bytes within the source file. This is the fastest way of getting at the file's contents, since no parsing or character encoding is performed or assumed.
