Struct TreeSlice 

pub struct TreeSlice<'a> { /* private fields */ }

A zero-copy borrowed view over a byte range of the tree. All offsets are relative to the slice start.

Implementations

impl<'a> TreeSlice<'a>

pub fn new(tree: &'a PieceTree, start: u32, end: u32) -> Self

pub fn len_bytes(&self) -> u32

pub fn len_chars(&self) -> u32

pub fn len_lines(&self) -> u32

pub fn chunks(&self) -> ChunkIter<'a>

Non-allocating chunk iterator over the slice’s byte range.

pub fn chars(&self) -> SliceChars<'a>

Non-allocating char iterator over the slice.

pub fn byte(&self, offset: u32) -> Option<u8>
