Trait Implementations

impl BitAnd<Boundary> for ColumnBoundaryFlags

type Output = bool

The resulting type after applying the & operator.

fn bitand(self, boundary: Boundary) -> bool

Performs the & operation.

impl BitOr<Boundary> for ColumnBoundaryFlags

type Output = ColumnBoundaryFlags

The resulting type after applying the | operator.

fn bitor(self, boundary: Boundary) -> Self

Performs the | operation.

impl Clone for Boundary

fn clone(&self) -> Boundary

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Boundary

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

Formats the value using the given formatter.

impl Default for Boundary

fn default() -> Boundary

Returns the “default value” for a type.

impl Display for Boundary

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

Formats the value using the given formatter.

impl PartialEq for Boundary

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

impl Copy for Boundary

impl Eq for Boundary

impl StructuralPartialEq for Boundary
