Method symbol

cranelift/jit/src/backend.rs:115–121

Define a symbol in the internal symbol table. The JIT will use the symbol table to resolve names that are declared, but not defined, in the module being compiled. A common example is external functions. With this method, functions and data can be exposed to the code being compiled which are defined by the host. If a symbol is defined more than once, the most recent definition will be retained.

(&mut self, name: K, ptr: *const u8)

    /// the current process for public symbols, followed by searching the
    /// platform's C runtime).
    pub fn symbol<K>(&mut self, name: K, ptr: *const u8) -> &mut Self
    where
        K: Into<String>,
    {
        self.symbols.insert(name.into(), SendWrapper(ptr));
        self
    }
