Trait Implementations

impl Clone for RowFilter

fn clone(&self) -> RowFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RowFilter

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

Formats the value using the given formatter.

impl Default for RowFilter

fn default() -> Self

Returns the “default value” for a type.

impl From<RowFilter> for Filter

fn from(value: RowFilter) -> Self

Converts to this type from the input type.

impl PartialEq for RowFilter

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