#[repr(transparent)]pub struct SendValue { /* private fields */ }
Expand description
A version of Value
for storing Send
types, that implements Send
itself.
See the module documentation for more details.
Implementations
Methods from Deref<Target = Value>
sourcepub fn get<'a, T>(
&'a self
) -> Result<T, <<T as FromValue<'_>>::Checker as ValueTypeChecker>::Error> where
T: FromValue<'a>,
pub fn get<'a, T>(
&'a self
) -> Result<T, <<T as FromValue<'_>>::Checker as ValueTypeChecker>::Error> where
T: FromValue<'a>,
Tries to get a value of type T
.
Returns Ok
if the type is correct.
sourcepub fn get_owned<T>(
&self
) -> Result<T, <<T as FromValue<'_>>::Checker as ValueTypeChecker>::Error> where
T: for<'b> FromValue<'b> + 'static,
pub fn get_owned<T>(
&self
) -> Result<T, <<T as FromValue<'_>>::Checker as ValueTypeChecker>::Error> where
T: for<'b> FromValue<'b> + 'static,
Tries to get a value of an owned type T
.
sourcepub fn is<T: StaticType>(&self) -> bool
pub fn is<T: StaticType>(&self) -> bool
Returns true
if the type of the value corresponds to T
or is a sub-type of T
.
sourcepub fn is_type(&self, type_: Type) -> bool
pub fn is_type(&self, type_: Type) -> bool
Returns true
if the type of the value corresponds to type_
or is a sub-type of type_
.
sourcepub fn transform<T: ValueType>(&self) -> Result<Value, BoolError>
pub fn transform<T: ValueType>(&self) -> Result<Value, BoolError>
Tries to transform the value into a value of the target type
Tries to cast the contents of self
into a type appropriate
to store in dest_value
, e.g. to transform a G_TYPE_INT
value
into a G_TYPE_FLOAT
value. Performing transformations between
value types might incur precision lossage. Especially
transformations into strings might reveal seemingly arbitrary
results and shouldn’t be relied upon for production code (such
as rcfile value or object property serialization).
dest_value
Target value.
Returns
Whether a transformation rule was found and could be applied.
Upon failing transformations, dest_value
is left untouched.
