Expand description

Trait containing manually implemented methods of ContentProvider.

Provided Methods§

Source

fn value(&self, type_: Type) -> Result<Value, Error>

Gets the contents of @self stored in @value.

The @value will have been initialized to the GType the value should be provided in. This given GType does not need to be listed in the formats returned by ContentProviderExt::formats(). However, if the given GType is not supported, this operation can fail and G_IO_ERROR_NOT_SUPPORTED will be reported.

§Returns

true if the value was set successfully. Otherwise @error will be set to describe the failure.

§value

the GValue to fill

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
