Trait AnyVarValue 

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

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

Implementations

impl dyn AnyVarValue

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

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

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

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

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

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

Trait Implementations

impl PartialEq for dyn AnyVarValue

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

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
