fn output() -> Self
fn from_residual(residual: Self::Residual) -> Self
fn from_branch(b: ControlFlow<Self::Residual>) -> Self
fn branch(self) -> ControlFlow<Self::Residual>
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.
