[−][src]Struct glib::variant::Variant
A generic immutable value capable of carrying various types.
See the module documentation for more details.
Methods
impl Variant
[src]
pub fn type_(&self) -> &VariantTy
[src]
Returns the type of the value.
pub fn is<T: StaticVariantType>(&self) -> bool
[src]
Returns true
if the type of the value corresponds to T
.
pub fn get<T: FromVariant>(&self) -> Option<T>
[src]
Tries to extract a value of type T
.
Returns Some
if T
matches the variant's type.
pub fn get_str(&self) -> Option<&str>
[src]
Tries to extract a &str
.
Returns Some
if the variant has a string type (s
, o
or g
type
strings).
