Trait Implementations

impl Clone for Box

fn clone(&self) -> Self

Copies the inline boxed type by value with the type-specific copy function.

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

Performs copy-assignment from source.

impl Debug for Box

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

Formats the value using the given formatter.

impl Default for Box

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for Box

type ParamSpec = ParamSpecBoxed

type SetValue = Box

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecBoxedBuilder<'_, Box>
