Trait LibSpecifier

pub trait LibSpecifier {
    // Required method
    fn load_lib(spec: Self) -> Result<Library>;
}

Describes how to load a library from a given value for a lib X = Expr; statement in the lazy_extern! declaration. For &str or &OsStr it calls Library::new and passes the string as the library name to load. More complicated expressions are also allowed with brackets, as long as it evaluates to a type implementing LibSpecifier.

Required Methods

fn load_lib(spec: Self) -> Result<Library>

Load the library

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
