Trait Implementations

impl<'a> Clone for RopeyCursor<'a>

fn clone(&self) -> RopeyCursor<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Cursor for RopeyCursor<'_>

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

Returns the current chunk. If utf8_aware returns true then this function must never return a chunk that splits a unicode codepoint. See utf8_aware for details.

fn advance(&mut self) -> bool

Advances the cursor to the next chunk if possible. In that case true must be returned. If the end of data is reached this function should return false and not change the chunk

fn backtrack(&mut self) -> bool

Moves the cursor to the previous chunk if possible. In that case true must be returned If the start of data is reached this function should return false and not change the chunk

fn utf8_aware(&self) -> bool

Whether this cursor is aware of utf-8 codepoint boundaries.

fn total_bytes(&self) -> Option<usize>

Returns the total length of the data. This does not take the current cursor position into account and should not change with calls to advance and backtrack.

fn offset(&self) -> usize

The offset of the current chunk from the start of the haystack in bytes
