pub capture_kind: UpvarCapture,
}
Expand description
Part of MinCaptureInformationMap
; describes the capture kind (&, &mut, move)
for a particular capture as well as identifying the part of the source code
that triggered this capture to occur.
Fields§
§capture_kind_expr_id: Option<HirId>
Expr Id pointing to use that resulted in selecting the current capture kind
Eg:
let mut t = (0,1);
let c = || {
println!("{t:?}"); // L1
t.1 = 4; // L2
};
capture_kind_expr_id
will point to the use on L2 and path_expr_id
will point to the
use on L1.
If the user doesn’t enable feature capture_disjoint_fields
(RFC 2229) then, it is
possible that we don’t see the use of a particular place resulting in capture_kind_expr_id being
None. In such case we fallback on uvpars_mentioned for span.
Eg:
let x = 5;
let c = || {
let _ = x;
};
In this example, if capture_disjoint_fields
is not set, then x will be captured,
but we won’t see it being used during capture analysis, since it’s essentially a discard.
path_expr_id: Option<HirId>
Expr Id pointing to use that resulted the corresponding place being captured
See capture_kind_expr_id
for example.
capture_kind: UpvarCapture
Capture mode that was selected
