Expand description

Visitor struct used for tracking down dereferencing and borrowing of closure’s args

Fields

cx: &'a LateContext<'tcx>

The late context of the lint

closure_span: Span

The span of the input closure to adapt

closure_arg_is_type_annotated_double_ref: bool

Indicates if the arg of the closure is a type annotated double reference

next_pos: BytePos

last position of the span to gradually build the suggestion

suggestion_start: String

starting part of the gradually built suggestion

applicability: Applicability

confidence on the built suggestion

Implementations

build final suggestion:

  • create the ending part of suggestion
  • concatenate starting and ending parts
  • potentially remove needless borrowing

indicates whether the function from parent_expr takes its args by double reference

The value found at place is being borrowed with kind bk. diag_expr_id is the id used for diagnostics (see consume for more details). Read more
The path at assignee_place is being assigned to. diag_expr_id is the id used for diagnostics (see consume for more details). Read more
The place should be a fake read because of specified cause.
The value found at place is being copied. diag_expr_id is the id used for diagnostics (see consume for more details). Read more
