Trait proc_macro_error::ResultExt

pub trait ResultExt {
    type Ok;

    // Required methods
    fn unwrap_or_abort(self) -> Self::Ok;
    fn expect_or_abort(self, msg: &str) -> Self::Ok;
}

This traits expands Result<T, Into<Diagnostic>> with some handy shortcuts.

Required Methods

fn unwrap_or_abort(self) -> Self::Ok

Behaves like Result::unwrap: if self is Ok yield the contained value, otherwise abort macro execution via abort!.

fn expect_or_abort(self, msg: &str) -> Self::Ok

Behaves like Result::expect: if self is Ok yield the contained value, otherwise abort macro execution via abort!. If it aborts then resulting error message will be preceded with message.
