Trait ExpectInternal 

pub trait ExpectInternal<T> {
    // Required method
    fn expect_internal(self, msg: &str) -> Result<T, HintedString>;
}

Adds a method analogous to Option::expect that raises an internal compiler error instead of panicking.

Required Methods

fn expect_internal(self, msg: &str) -> Result<T, HintedString>

Extracts the value, producing an internal error if self is None.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
