) -> &'ll Value
🔬 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?
Declare a C ABI function.
Only use this for foreign function ABIs and glue. For Rust functions use
declare_fn
instead.
If there’s a value with the same name already declared, the function will update the declaration and return existing Value instead.
