Trait Implementations

impl Debug for Inst

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl NotUnboxable for Inst

impl Obj for Inst

fn dyn_objtype(self: Gc<Self>) -> ObjType

What ObjType does this Val represent?

fn get_class(self: Gc<Self>, _: &mut VM) -> Val

What class is this object an instance of?

fn num_inst_vars(self: Gc<Self>, vm: &VM) -> usize

unsafe fn unchecked_inst_var_set(self: Gc<Self>, vm: &VM, n: usize, v: Val)

Set an instance variable in this object. If usize exceeds the number of instance variables this will lead to undefined behaviour.

fn hashcode(self: Gc<Self>) -> u64

What is this object’s hashcode?

fn to_array(self: Gc<Self>) -> Result<Gc<dyn Array>, Box<VMError>> where
    Self: Send, 

If (and only if) this object implements the Array trait then return a reference to this object as an Array trait object.

fn to_strval(self: Gc<Self>, _: &mut VM) -> Result<Val, Box<VMError>> where
    Self: Send,

    Self: Send, 

Return the instance variable at i (using SOM indexing).

fn inst_var_at_put(
    self: Gc<Self>,
    vm: &VM,
    i: usize,

    Self: Send, 

Produce a new Val which performs a mod operation on this with other.

fn mul(self: Gc<Self>, _: &mut VM, _: Val) -> Result<Val, Box<VMError>> where
    Self: Send,

fn shl(self: Gc<Self>, _: &mut VM, _: Val) -> Result<Val, Box<VMError>> where
    Self: Send, 

Produce a new Val which shifts self other bits to the left.

fn shr(self: Gc<Self>, _: &mut VM, _: Val) -> Result<Val, Box<VMError>> where
    Self: Send, 

Produce a new Val which shifts self other bits to the right, treating self as if it did not have a sign bit.

fn sqrt(self: Gc<Self>, _: &mut VM) -> Result<Val, Box<VMError>> where
    Self: Send, 

Produces a new Val which is the square root of this.

fn sub(self: Gc<Self>, _: &mut VM, _: Val) -> Result<Val, Box<VMError>> where
