Enum NavKind 

#[repr(u8)]
pub enum NavKind {

}

Navigation kind determining movement direction and skip policy.

Variants

Stay = 0

No movement. Used only for first transition when cursor is at root.

Next = 1

Skip any nodes to find match.

NextSkipTrivia = 2

Skip trivia only, fail if non-trivia skipped.

NextExact = 3

No skipping, current sibling must match.

Down = 4

Skip any among children.

DownSkipTrivia = 5

Skip trivia only among children.

DownExact = 6

First child must match, no skip.

Up = 7

Ascend level levels, no constraint.

UpSkipTrivia = 8

Validate last non-trivia, ascend level levels.

UpExact = 9

Validate last child, ascend level levels.

Trait Implementations

impl Clone for NavKind

fn clone(&self) -> NavKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NavKind

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

Formats the value using the given formatter.

impl PartialEq for NavKind

fn eq(&self, other: &NavKind) -> 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.
