[][src]Function rustc::ty::context::tls::set_tlv

fn set_tlv<F: FnOnce() -> R, R>(value: usize, f: F) -> R
🔬 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?

Sets TLV to value during the call to f. It is restored to its previous value after. This is used to set the pointer to the new ImplicitCtxt.
