Enum rustc_trait_selection::infer::RegionckMode

source · [−]

pub enum RegionckMode {
    Solve,
    Erase {
        suppress_errors: bool,
    },
}

Expand description

How we should handle region solving.

This is used so that the region values inferred by HIR region solving are not exposed, and so that we can avoid doing work in HIR typeck that MIR typeck will also do.

Variants

`Solve`

The default mode: report region errors, don’t erase regions.

`Erase`

Fields

suppress_errors: bool

A flag that is used to suppress region errors, when we are doing region checks that the NLL borrow checker will also do – it might be set to true.

Erase the results of region after solving.
