A version of Value for storing Send types, that implements Send itself.

See the module documentation for more details.

Methods

impl SendValue[−]

pub fn downcast<'a, T: FromValueOptional<'a> + SetValue + Send>(
    self
) -> Result<TypedValue<T>, Self>[−]

Tries to downcast to a TypedValue.

Returns Ok(TypedValue<T>) if the value carries a type corresponding to T and Err(self) otherwise.

pub fn downcast_ref<'a, T: FromValueOptional<'a> + SetValue>(
    &self
) -> Option<&TypedValue<T>>[−]

Tries to downcast to a &TypedValue.

Returns Some(&TypedValue<T>) if the value carries a type corresponding to T and None otherwise.

Methods from Deref<Target = Value>

pub fn downcast_ref<'a, T: FromValueOptional<'a> + SetValue>(
    &self
) -> Option<&TypedValue<T>>[−]

Tries to downcast to a &TypedValue.

Returns Some(&TypedValue<T>) if the value carries a type corresponding to T and None otherwise.

pub fn get<'a, T: FromValueOptional<'a>>(
    &'a self
) -> Result<Option<T>, GetError>[−]

Tries to get a possibly optional value of type T.

Returns Ok if the type is correct.

pub fn get_some<'a, T: FromValue<'a>>(&'a self) -> Result<T, GetError>[−]

Tries to get a value of type T.

This method is only available for types that don't support a None value.

Returns Ok if the type is correct.

pub fn is<'a, T: FromValueOptional<'a> + SetValue>(&self) -> bool[−]

Returns true if the type of the value corresponds to T or is a sub-type of T.

pub fn type_(&self) -> Type[−]

Returns the type of the value.

pub fn transform<T: StaticType + SetValue>(&self) -> Option<Value>[−]

Tries to transform the value into a value of the target type
