struct ParamPosition {
    value: usize,
    width: Option<usize>,
    precision: Option<usize>,
}
Expand description

The positions of a format argument’s value, precision and width

A position is an index into the second argument of Arguments::new_v1[_formatted]

Fields§

§value: usize

The position stored in rt::v1::Argument::position.

§width: Option<usize>

The position stored in rt::v1::FormatSpec::width if it is a Count::Param.

§precision: Option<usize>

The position stored in rt::v1::FormatSpec::precision if it is a Count::Param.

impl<'tcx> Visitor<'tcx> for ParamPosition

source§

fn visit_expr_field(&mut self, field: &'tcx ExprField<'tcx>)

§

type Map = <Self::NestedFilter as NestedFilter<'v>>::Map

§

type NestedFilter = None

Override this type to control which nested HIR are visited; see NestedFilter for details. If you override this type, you must also override nested_visit_map. Read more
source§

fn nested_visit_map(&mut self) -> Self::Map

If type NestedFilter is set to visit nested items, this method must also be overridden to provide a map to retrieve nested items.
source§

fn visit_nested_item(&mut self, id: ItemId)

Invoked when a nested item is encountered. By default, when Self::NestedFilter is nested_filter::None, this method does nothing. You probably don’t want to override this method – instead, override Self::NestedFilter or use the “shallow” or “deep” visit patterns described on itemlikevisit::ItemLikeVisitor. The only reason to override this method is if you want a nested pattern but cannot supply a Map; see nested_visit_map for advice.
source§

fn visit_nested_trait_item(&mut self, id: TraitItemId)

Like visit_nested_item(), but for trait items. See visit_nested_item() for advice on when to override this method.
source§

fn visit_nested_impl_item(&mut self, id: ImplItemId)

Like visit_nested_item(), but for impl items. See visit_nested_item() for advice on when to override this method.
source§

fn visit_nested_foreign_item(&mut self, id: ForeignItemId)

Like visit_nested_item(), but for foreign items. See visit_nested_item() for advice on when to override this method.
source§

fn visit_nested_body(&mut self, id: BodyId)

Invoked to visit the body of a function, method or closure. Like visit_nested_item, does nothing by default unless you override Self::NestedFilter.

fn visit_item(&mut self, i: &'v Item<'v>)
