pub enum Feature<'a> {
    With(&'a str),
    Without(&'a str),
}
Expand description

A cranelift feature in a test file preamble.

This represents the expectation of the test case. Before running any of the functions of the test file, the feature set should be compared with the feature set used to compile Cranelift. If there is any differences, then the test file should be skipped.

Variants§

§

With(&'a str)

feature "..." lines

§

Without(&'a str)

feature ! "..." lines.

fn eq(&self, other: &Feature<'a>) -> bool

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
