A parsed format_args! expansion

Fields

format_string_span: Span

Span of the first argument, the format string

value_args: Vec<&'tcx Expr<'tcx>>

Values passed after the format string

format_string_parts: &'tcx [Expr<'tcx>]

String literal expressions which represent the format string split by “{}”

format_string_symbols: Vec<Symbol>

Symbols corresponding to Self::format_string_parts

args: &'tcx [Expr<'tcx>]

Expressions like ArgumentV1::new(arg0, Debug::fmt)

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

The final argument passed to Arguments::new_v1_formatted, if applicable

Implementations

impl<'tcx> FormatArgsExpn<'tcx>

pub fn parse(expr: &'tcx Expr<'tcx>) -> Option<Self>

Parses an expanded format_args! or format_args_nl! invocation

pub fn args(&self) -> Option<Vec<FormatArgsArg<'tcx>>>

Returns a vector of FormatArgsArg.

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.
