doc-comment leader: ///

Set a Rust function taking a reference to the scripting Engine
,
the current set of functions, plus a list of mutable Dynamic
references
into the Module
, returning a u64
hash key.
Use this to register a built-in function which must reference settings on the scripting
Engine
(e.g. to prevent growing an array beyond the allowed maximum size),
or to call a script-defined function in the current evaluation context.
If there is a similar existing Rust function, it is replaced.
WARNING - Low Level API
This function is very low level.
Arguments
A list of TypeId
’s is taken as the argument types.
Arguments are simply passed in as a mutable array of &mut Dynamic
,
which is guaranteed to contain enough arguments of the correct types.
The function is assumed to be a method, meaning that the first argument should not be consumed. All other arguments can be consumed.
To access a primary argument value (i.e. cloning is cheap), use: args[n].as_xxx().unwrap()
To access an argument value and avoid cloning, use std::mem::take(args[n]).cast::<T>()
.
Notice that this will consume the argument, replacing it with ()
.
To access the first mutable argument, use args.get_mut(0).unwrap()
Function Metadata
No metadata for the function is registered. Use update_fn_metadata
to add metadata.
Example
use rhai::{Module, FnNamespace, FnAccess};
let mut module = Module::new();
let hash = module.set_raw_fn("double_or_not", FnNamespace::Internal, FnAccess::Public,
// Pass parameter types via a slice with TypeId's
&[std::any::TypeId::of::<i64>(), std::any::TypeId::of::<bool>()],
// Fixed closure signature
|context, args| {
// 'args' is guaranteed to be the right length and of the correct types
// Get the second parameter by 'consuming' it
let double = std::mem::take(args[1]).cast::<bool>();
// Since it is a primary type, it can also be cheaply copied
let double = args[1].clone_cast::<bool>();
// Get a mutable reference to the first argument.
let mut x = args[0].write_lock::<i64>().unwrap();
let orig = *x;
if double {
*x *= 2; // the first argument can be mutated
}
Ok(orig) // return RhaiResult<T>
});
