Trait AnyVarValue 

pub trait AnyVarValue:
    Debug
    + Any
    + Send
    + Sync {
    // Required methods
    fn clone_boxed(&self) -> BoxAnyVarValue;
    fn eq_any(&self, other: &(dyn AnyVarValue + 'static)) -> bool;
    fn type_name(&self) -> &'static str;
    fn try_swap(&mut self, other: &mut (dyn AnyVarValue + 'static)) -> bool;
}

Represents any variable value.

Trait Alias

This trait is used like a type alias for traits and is already implemented for all types it can apply to.

See VarValue<T> for more details.

Required Methods

fn clone_boxed(&self) -> BoxAnyVarValue

Clone the value.

fn eq_any(&self, other: &(dyn AnyVarValue + 'static)) -> bool

Gets if self and other are equal.

fn type_name(&self) -> &'static str

Value type name.

Note that this string is not stable and should be used for debug only.

fn try_swap(&mut self, other: &mut (dyn AnyVarValue + 'static)) -> bool

Swap value with other if both are of the same type.

Implementations

impl dyn AnyVarValue

pub fn downcast_ref<T>(&self) -> Option<&T>

where T: VarValue,

Returns some reference to the inner value if it is of type T, or None if it isn’t.

pub fn downcast_mut<T>(&mut self) -> Option<&mut T>

where T: VarValue,

Returns some mutable reference to the inner value if it is of type T, or None if it isn’t.

pub fn is<T>(&self) -> bool

where T: VarValue,

Returns true if the inner type is the same as T.

Trait Implementations

impl PartialEq for dyn AnyVarValue

fn eq(&self, other: &(dyn AnyVarValue + 'static)) -> 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.
