Struct CaretPosition 

pub struct CaretPosition {
    pub index: usize,
    pub affinity: CaretAffinity,
}

A position between characters, given as a UTF-8 byte index plus the side it attaches to.

The index alone is ambiguous at a soft wrap or a bidi boundary, because the same byte can sit at the end of one row or the start of the next. The affinity decides which.

Fields

index: usize

The logical UTF-8 byte index.

affinity: CaretAffinity

The logical neighbor that owns this position.

Implementations

pub const fn attached_to_next_cluster(index: usize) -> Self

pub const fn attached_to_previous_cluster(index: usize) -> Self

Creates a caret attached to the previous logical cluster.
