pub struct BoxedValue(pub Value);
Expand description

A Value containing another Value.

Tuple Fields§

§0: Value

Methods from Deref<Target = Value>§

Tries to get a value of type T.

Returns Ok if the type is correct.

Tries to get a value of an owned type T.

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

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

Returns the type of the value.

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.

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