Module rustc_mir_transform::simplify_try[−][src]

Expand description

The general point of the optimizations provided here is to simplify something like:

match x {
    Ok(x) => Ok(x),
    Err(x) => Err(x)
}

into just x.

Structs

Simplifies arms of form Variant(x) => Variant(x) to just a move.

Simplifies SwitchInt(_) -> [targets], where all the targets have the same form, into goto -> target_first.
