Expand description
A FormatParam
is any place in a FormatArgument
that refers to a supplied value, e.g.
let precision = 2;
format!("{:.precision$}", 0.1234);
has two FormatParam
s, a FormatParamKind::Implicit
.kind
with a .value
of 0.1234
and a [FormatParamKind::NamedInline("precision")
] .kind
with a .value
of 2
Fields
value: &'tcx Expr<'tcx>
The expression this parameter refers to.
kind: FormatParamKind
How this parameter refers to its value
.
span: Span
Span of the parameter, may be zero width. Includes the whitespace of implicit parameters.
format!("{}, { }, {0}, {name}", ...);

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
