Enum rustc_infer::infer::RegionckMode[−][src]

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

Erase the results of region after solving.

Fields of Erase

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.

Implementations

[src]

impl RegionckMode

[src]

pub fn for_item_body(tcx: TyCtxt<'_>) -> Self

Indicates that the MIR borrowck will repeat these region checks, so we should ignore errors if NLL is (unconditionally) enabled.
