Enum MirIncludeSpans

Source 
pub enum MirIncludeSpans {
    Off,
    On,
    Nll,
}
Expand description

Whether extra span comments are included when dumping MIR, via the -Z mir-include-spans flag. By default, only enabled in the NLL MIR dumps, and disabled in all other passes.

Variants§

§

Off

§

On

§

Nll

Default: include extra comments in NLL MIR dumps only. Can be ignored and considered as Off in all other cases.

Implementations§

Source§

impl MirIncludeSpans

Source

pub fn is_enabled(self) -> bool

Unless opting into extra comments for all passes, they can be considered disabled. The cases where a distinction between on/off and a per-pass value can exist will be handled in the passes themselves: i.e. the Nll value is considered off for all intents and purposes, except for the NLL MIR dump pass.
