pub trait TryStaticCast: Sized + 'static {
// Provided methods
fn type_eq<U: TryStaticCast>() -> bool { ... }
fn try_cast<U: TryStaticCast>(self) -> Option<U> { ... }
fn try_cast_ref<U: TryStaticCast>(&self) -> Option<&U> { ... }
}Expand description
Use to transfer objects from one generic type to another, without the compiler being able to determine whether or not the two types are the same. The cast is statically dispatched.
Provided Methods§
fn type_eq<U: TryStaticCast>() -> bool
fn try_cast<U: TryStaticCast>(self) -> Option<U>
fn try_cast_ref<U: TryStaticCast>(&self) -> Option<&U>
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.
