Enum TextUnit

pub enum TextUnit {
    Utf8,
    Line,
}

The unit of measure when requesting data.

Variants

Utf8

The requested offset is in bytes. The returned chunk will be valid UTF8, and is guaranteed to include the byte specified the offset.

Line

The requested offset is a line number. The returned chunk will begin at the offset of the requested line.

Implementations

impl TextUnit

pub fn resolve_offset<T: Borrow<Rope>>( self, text: T, offset: usize, ) -> Option<usize>

Converts an offset in some unit to a concrete byte offset. Returns None if the input offset is out of bounds in its unit space.
