}Expand description
A Named type is a type that has a globally unique name.
Required Methods§
Provided Methods§
fn typeid() -> TypeId
fn typeid() -> TypeId
The TypeId for this type. TypeIds are unique only within a binary, and should not be used for global identification.
fn port() -> u64
fn port() -> u64
The globally unique port for this type. Typed ports are in the range of 1<<63..1<<64-1.
fn arm(&self) -> Option<&'static str>
fn arm(&self) -> Option<&'static str>
If the named type is an enum, this returns the name of the arm of the value self.
unsafe fn arm_unchecked(self_: *const ()) -> Option<&'static str>
unsafe fn arm_unchecked(self_: *const ()) -> Option<&'static str>
An unsafe version of ‘arm’, accepting a pointer to the value, for use in type-erased settings.
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.
