[−][src]Struct gluon::Thread
Representation of the virtual machine
Methods
impl Thread
[src]
pub fn new_thread(&self) -> Result<RootedThread, Error>
[src]
Spawns a new gluon thread with its own stack and heap but while still sharing the same global environment
pub fn root_thread(&self) -> RootedThread
[src]
Roots self
, extending the lifetime of this thread until at least the returned
RootedThread
is droppped
pub fn get_global<'vm, T>(&'vm self, name: &str) -> Result<T, Error> where
T: Getable<'vm, 'value> + VmType,
[src]
T: Getable<'vm, 'value> + VmType,
Retrieves the global called name
.
Examples
Bind the (+)
function in gluon's prelude standard library
to an add
function in rust
let vm = new_vm(); vm.run_expr::<OpaqueValue<&Thread, Hole>>("example", r#" import! std.int "#) .unwrap_or_else(|err| panic!("{}", err)); let mut add: FunctionRef<fn(i32, i32) -> i32> = vm.get_global("std.int.num.(+)").unwrap(); let result = add.call(1, 2); assert_eq!(result, Ok(3));
Errors
if the global does not exist or it does not have the correct type.
