pub fn modern(self) -> Ident

🔬 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?

"Normalize" ident for use in comparisons using "item hygiene". Identifiers with same string value become same if they came from the same "modern" macro (e.g. macro item, but not macro_rules item) and stay different if they came from different "modern" macros. Technically, this operation strips all non-opaque marks from ident's syntactic context.

🔬 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?

"Normalize" ident for use in comparisons using "local variable hygiene". Identifiers with same string value become same if they came from the same non-transparent macro (e.g. macro or macro_rules! items) and stay different if they came from different non-transparent macros. Technically, this operation strips all transparent marks from ident's syntactic context.
