Struct passerine::core::ffi::FFI

pub struct FFI(_);

A foreign functional interface, mapping names to functions, passed to the compiler at the bytecode generation step.

Implementations

impl FFI

pub fn new() -> FFI

Creates a new empty Foreign Functional Interface.

impl FFI

pub fn add(&mut self, name: &str, function: FFIFunction) -> Result<(), String>

Returns true if the function has already been added to the FFI.

pub fn get(&mut self, name: &str) -> Result<FFIFunction, String>

Returns the FFIFunction interned with the provided name.

pub fn combine(&mut self, other: FFI) -> Result<(), FFI>

Tries to merge one FFI into another. If there was a name collision, this function returns an Err(FFI) with the functions that collided.
