Struct artichoke_backend::Artichoke

pub struct Artichoke {
    pub mrb: NonNull<mrb_state>,
    pub state: Option<Box<State>>,
}

Interpreter instance.

Functionality is added to the interpreter via traits, for example, garbage collection or eval.

Fields

mrb: NonNull<mrb_state>

Underlying mruby interpreter.

This is an owned reference to the interpreter via a mutable pointer.

state: Option<Box<State>>

Interpreter state.

This field is an Option because the State is moved in and out of the Artichoke struct as the call graph crosses between Rust and C and C to Rust.

Implementations

impl Artichoke

pub const fn new(mrb: NonNull<mrb_state>, state: Box<State>) -> Self

Create a new interpreter from an underlying mrb and a State.

pub fn protect(&mut self, value: Value) -> Value

Prevent the given value from being garbage collected.

Calls sys::mrb_gc_protect on this value which adds it to the GC arena. This object will remain in the arena until ArenaIndex::restore restores the arena to an index before this call to protect.

pub unsafe fn with_ffi_boundary<F, T>( &mut self, func: F ) -> Result<T, InterpreterExtractError>

where F: FnOnce(*mut mrb_state) -> T,

Execute a a closure by moving the State into the mrb instance.

This method prepares this interpreter to cross an FFI boundary. When the Artichoke implementation calls mruby FFI functions, the State must be moved into the sys::mrb_state userdata pointer.

Safety

This method moves the State out of this instance into the mrb instance. During this function’s execution, this instance may be partially initialized.

This function is only safe to call if the closure only calls FFI functions that use a raw *mut sys::mrb_state.

pub unsafe fn into_raw(interp: Self) -> *mut mrb_state

Consume an interpreter and return the pointer to the underlying sys::mrb_state.

This function does not free any interpreter resources. Its intended use is to prepare the interpreter to cross over an FFI boundary.

This is an associated function and must be called as Artichoke::into_raw(interp).

Safety

After calling this function, the caller is responsible for properly freeing the memory occupied by the interpreter heap. The easiest way to do this is to call ffi::from_user_data with the returned pointer and then call Artichoke::close.

pub fn close(self)

Consume an interpreter and free all live objects.
