Enum Affinity 

#[non_exhaustive]
pub enum Affinity {
    Downstream,
    Upstream,
}

Which character a caret at a position belongs to, where that matters: at a line wrap (end of one line or start of the next) and at a change of text direction.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Downstream

With the character after the position (start of the next line at a wrap).

Upstream

With the character before the position (end of the line at a wrap): where a caret stays after typing at the end of a wrapped line.
