Enum SelectionBoundary

#[non_exhaustive]
pub enum SelectionBoundary {
    Line,
    NonWhitespace,
}

Different ways to expand or trim selections.

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.

Line

A selection that starts at the beginning of a line and ends on a newline.

NonWhitespace

A selection that starts on a non-whitespace character and ends on a non-whitespace character.

Trait Implementations

impl BoundaryTest for SelectionBoundary

fn is_boundary_begin(&self, ctx: &BoundaryTestContext) -> bool

Check whether we are at the beginning of the range.

fn is_boundary_end(&self, ctx: &BoundaryTestContext) -> bool

Check whether we are at the end of the range.

fn is_boundary(&self, terminus: MoveTerminus, ctx: &BoundaryTestContext) -> bool

Check whether we are at the given side of the range.

impl Clone for SelectionBoundary

fn clone(&self) -> SelectionBoundary

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelectionBoundary

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

Formats the value using the given formatter.

impl PartialEq for SelectionBoundary

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