Struct boa::gc::GcObject

pub struct GcObject(_);

Garbage collected Object.

Implementations

impl GcObject

pub fn new(object: Object) -> Self

Create a new GcObject from a Object.

pub fn borrow(&self) -> Ref<'_>

Immutably borrows the Object.

The borrow lasts until the returned GcCellRef exits scope. Multiple immutable borrows can be taken out at the same time.

Panics

Panics if the object is currently mutably borrowed.

pub fn borrow_mut(&self) -> RefMut<'_>

Mutably borrows the Object.

The borrow lasts until the returned GcCellRefMut exits scope. The object cannot be borrowed while this borrow is active.

Panics

Panics if the object is currently borrowed.

pub fn try_borrow(&self) -> StdResult<Ref<'_>, BorrowError>

Immutably borrows the Object, returning an error if the value is currently mutably borrowed.

The borrow lasts until the returned GcCellRef exits scope. Multiple immutable borrows can be taken out at the same time.

This is the non-panicking variant of borrow.

pub fn try_borrow_mut(&self) -> StdResult<RefMut<'_>, BorrowMutError>

Mutably borrows the object, returning an error if the value is currently borrowed.

The borrow lasts until the returned GcCellRefMut exits scope. The object be borrowed while this borrow is active.

This is the non-panicking variant of borrow_mut.

pub fn equals(lhs: &Self, rhs: &Self) -> bool

Checks if the garbage collected memory is the same.

pub fn call(
    &self,
    this: &Value,
    args: &[Value],
    ctx: &mut Context
) -> Result<Value>

Call this object.

Panics

Panics if the object is currently mutably borrowed.

pub fn construct(&self, args: &[Value], ctx: &mut Context) -> Result<Value>

Construct an instance of this object with the specified arguments.

Panics

Panics if the object is currently mutably borrowed.
