Enum ComponentCloneBehavior

pub enum ComponentCloneBehavior {
    Default,
    Ignore,
    Custom(fn(_: &SourceComponent<'_>, _: &mut ComponentCloneCtx<'_, '_>)),
}

The clone behavior to use when cloning a Component.

Variants

Default

Uses the default behavior (which is passed to ComponentCloneBehavior::resolve)

Ignore

Do not clone this component.

Custom(fn(_: &SourceComponent<'_>, _: &mut ComponentCloneCtx<'_, '_>))

Uses a custom ComponentCloneFn.

Implementations

impl ComponentCloneBehavior

pub fn clone<C>() -> ComponentCloneBehavior

where C: Component + Clone,

Set clone handler based on Clone trait.

If set as a handler for a component that is not the same as the one used to create this handler, it will panic.

pub fn reflect() -> ComponentCloneBehavior

Set clone handler based on Reflect trait.

pub fn global_default_fn() -> fn(_: &SourceComponent<'_>, _: &mut ComponentCloneCtx<'_, '_>)

Returns the “global default”

pub fn resolve( &self, default: fn(_: &SourceComponent<'_>, _: &mut ComponentCloneCtx<'_, '_>), ) -> fn(_: &SourceComponent<'_>, _: &mut ComponentCloneCtx<'_, '_>)

Resolves the ComponentCloneBehavior to a ComponentCloneFn. If ComponentCloneBehavior::Default is specified, the given default function will be used.

Trait Implementations

impl Clone for ComponentCloneBehavior

fn clone(&self) -> ComponentCloneBehavior

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentCloneBehavior

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

Formats the value using the given formatter.

impl Default for ComponentCloneBehavior

fn default() -> ComponentCloneBehavior

Returns the “default value” for a type.

impl PartialEq for ComponentCloneBehavior

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