Enum termwiz::lineedit::SearchDirection

source · [−]

pub enum SearchDirection {
    Backwards,
    Forwards,
}

Expand description

Encodes the direction the search should take, relative to the current HistoryIndex.

Variants

`Backwards`

The search goes backwards towards the smaller HistoryIndex values at the beginning of history.

`Forwards`

The search goes forwards towarrds the larger HistoryIndex values at the end of history.

Implementations

source

impl SearchDirection

source

pub fn next(self, idx: HistoryIndex) -> Option<HistoryIndex>

Given a history index, compute the next value in the encoded search directory. Returns None if the search would overflow.
