Trait Implementations

impl<R, C> CellOption<R, C> for EmptySettings

fn change(self, _: &mut R, _: &mut C, _: Entity)

Modification function of a certail part of a grid targeted by Entity.

fn hint_change(&self) -> Option<Entity>

A hint whether an TableOption is going to change table layout.

impl Clone for EmptySettings

fn clone(&self) -> EmptySettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EmptySettings

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

Formats the value using the given formatter.

impl Ord for EmptySettings

fn cmp(&self, other: &EmptySettings) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for EmptySettings

fn eq(&self, other: &EmptySettings) -> 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 PartialOrd for EmptySettings

fn partial_cmp(&self, other: &EmptySettings) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<R, D, C> TableOption<R, C, D> for EmptySettings

fn change(self, _: &mut R, _: &mut C, _: &mut D)

The function modificaties of records and a grid configuration.

fn hint_change(&self) -> Option<Entity>

A hint whether an TableOption is going to change table layout.
