Variants

Previous

Equivalent to BackwardWrapping(1), kept for backward compatibility.

Next

Equivalent to ForwardWrapping(1), kept for backward compatibility.

ForwardWrapping(usize)

Move the selection forward by usize items, wrapping around to the beginning if necessary.

Forward(usize)

Move the selection forward by usize items, clamping at the end if necessary.

BackwardWrapping(usize)

Move the selection backward by usize items, wrapping around to the end if necessary.

Backward(usize)

Move the selection backward by usize items, clamping at the beginning if necessary.

Beginning

Equivalent to JumpTo(0), but simpler in semantics.

End

Equivalent to JumpTo(usize::MAX), but simpler in semantics.

JumpTo(usize)

Jump to the usizeth item in the list, clamping at the beginning and end if necessary.

Trait Implementations

impl Clone for Navigation

fn clone(&self) -> Navigation

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Navigation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Navigation

fn eq(&self, other: &Navigation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
