pub fn expand_preparsed_format_args(
ecx: &mut ExtCtxt,

) -> P<Expr>
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
Take the various parts of format_args!(efmt, args..., name=names...)
and construct the appropriate formatting expression.
