Struct yksom::vm::objects::Int

pub struct Int { /* fields omitted */ }

A boxed isize.

Implementations

impl Int

pub fn boxed_isize(_: &mut VM, i: isize) -> Val

Create a Val representing the usize integer i. The Val is guaranteed to be boxed internally.

pub fn as_isize(&self) -> isize

pub fn as_usize(&self, vm: &VM) -> Result<usize, Box<VMError>>

Trait Implementations

impl Debug for Int

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

Formats the value using the given formatter.

impl Obj for Int

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

What ObjType does this Val represent?

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

What class is this object an instance of?

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

Convert this object to a Val that represents a SOM string.

fn add(self: Gc<Self>, vm: &mut VM, other: Val) -> Result<Val, Box<VMError>>

Produce a new Val which adds other to this.

fn div(self: Gc<Self>, vm: &mut VM, other: Val) -> Result<Val, Box<VMError>>

Produce a new Val which divides other from this.

fn mul(self: Gc<Self>, vm: &mut VM, other: Val) -> Result<Val, Box<VMError>>

Produce a new Val which multiplies other to this.

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

Produce a new Val which subtracts other from this.

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 num_inst_vars(self: Gc<Self>, _: &VM) -> usize where
    Self: Send, 

How many instance variables does this object contain?

fn inst_var_at(self: Gc<Self>, vm: &VM, i: usize) -> Result<Val, Box<VMError>> where
    Self: Send, 

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

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

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

unsafe fn unchecked_inst_var_get(self: Gc<Self>, _: &VM, _: usize) -> Val where
    Self: Send,

unsafe fn unchecked_inst_var_set(self: Gc<Self>, _: &VM, _: usize, _: Val) where
    Self: Send, 

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

    vm: &mut VM,
    other: Val
) -> Result<Val, Box<VMError>> where
    Self: Send,
