Struct gluon::RootedThread[][src]

pub struct RootedThread(_);

An instance of Thread which is rooted. See the Thread type for documentation on interacting with the type.

Methods

impl RootedThread
[src]

Creates a new virtual machine with an empty global environment

Converts a RootedThread into a raw pointer allowing to be passed through a C api. The reference count for the thread is not modified

Converts a raw pointer into a RootedThread. The reference count for the thread is not modified so it is up to the caller to ensure that the count is correct.

Methods from Deref<Target = Thread>

Spawns a new gluon thread with its own stack and heap but while still sharing the same global environment

Roots self, extending the lifetime of this thread until at least the returned RootedThread is droppped

Deprecated since 0.7.0

: Use gluon::import::add_extern_module instead

Creates a new global value at name. Fails if a global called name already exists.

Examples

Load the factorial rust function into gluon and evaluate factorial 5

fn factorial(x: i32) -> i32 {
    if x <= 1 { 1 } else { x * factorial(x - 1) }
}


let vm = new_vm();

vm.define_global("factorial", primitive!(1, factorial)).unwrap();

let result = Compiler::new()
    .run_expr::<i32>(&vm, "example", "factorial 5")
    .unwrap_or_else(|err| panic!("{}", err));
let expected = (120, Type::int());

assert_eq!(result, expected);

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();

Compiler::new()
    .run_expr::<OpaqueValue<&Thread, Hole>>(&vm, "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.

Retrieves type information about the type name. Types inside records can be accessed using dot notation (std.prelude.Option)

Returns the gluon type that was bound to T

Registers the type T as being a gluon type called name with generic arguments args

Locks and retrieves the global environment of the vm

Retrieves the macros defined for this vm

Runs a garbage collection.

Pushes a value to the top of the stack

Removes the top value from the stack

Trait Implementations

impl VmType for RootedThread
[src]

A version of Self which implements Any allowing a TypeId to be retrieved

Creates an gluon type which maps to Self in rust

How many extra arguments a function returning this type requires. Used for abstract types which when used in return position should act like they still need more arguments before they are called Read more

impl<'a> VmRoot<'a> for RootedThread
[src]

Roots a value

impl Drop for RootedThread
[src]

Executes the destructor for this type. Read more

impl<'vm> Pushable<'vm> for RootedThread
[src]

Pushes self to stack. If the call is successful a single element should have been added to the stack and Ok(()) should be returned. If the call is unsuccessful Status:Error should be returned and the stack should be left intact Read more

[src]

impl Deref for RootedThread
[src]

The resulting type after dereferencing.

Dereferences the value.

impl Debug for RootedThread
[src]

[src]

Returns a copy of the value. Read more
