Expand description

GLib error domain.

This trait is implemented by error enums that represent error domains (types).

Required Methods§

Source

fn domain() -> Quark

Returns the quark identifying the error domain.

As returned from g_some_error_quark.

Source

fn code(self) -> i32

Gets the integer representation of the variant.

Source

fn from(code: i32) -> Option<Self>
where Self: Sized,

Tries to convert an integer code to an enum variant.

By convention, the Failed variant, if present, is a catch-all, i.e. any unrecognized codes map to it.

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.
