Struct clippy_utils::higher::FormatArgsArg

pub struct FormatArgsArg<'tcx> {
    pub value: &'tcx Expr<'tcx>,
    pub arg: &'tcx Expr<'tcx>,
    pub fmt: Option<&'tcx Expr<'tcx>>,
}

Type representing a FormatArgsExpn’s format arguments

Fields

value: &'tcx Expr<'tcx>

An element of value_args according to position

arg: &'tcx Expr<'tcx>

An element of args according to position

fmt: Option<&'tcx Expr<'tcx>>

An element of fmt_expn

Implementations

impl<'tcx> FormatArgsArg<'tcx>

pub fn has_string_formatting(&self) -> bool

Returns true if any formatting parameters are used that would have an effect on strings, like {:+2} instead of just {}.

pub fn is_display(&self) -> bool

Returns true if the argument is formatted using Display::fmt.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
