Enum rustc_typeck::check::upvar::UpvarMigrationInfo
source · enum UpvarMigrationInfo {
CapturingPrecise {
source_expr: Option<HirId>,
var_name: String,
},
CapturingNothing {
use_span: Span,
},
}
Expand description
Intermediate format to store the hir_id pointing to the use that resulted in the corresponding place being captured and a String which contains the captured value’s name (i.e: a.b.c)
Variants
CapturingPrecise
We previously captured all of x
, but now we capture some sub-path.
