Struct yksom::vm::objects::NormalArray

pub struct NormalArray { /* fields omitted */ }

Implementations

impl NormalArray

pub fn new(vm: &VM, len: usize) -> Val

pub fn from_vec(v: Vec<Val>) -> Val

pub unsafe fn alloc<F>(len: usize, init: F) -> Val where
    F: FnOnce(*mut Val), 

Create a new NormalArray with a backing store of len elements. init will be called with a pointer to the uninitialised backing store. After init completes, the backing store will be considered fully initialised: failure to fully initialise it causes undefined behaviour.

Trait Implementations

impl Array for NormalArray

fn at(self: Gc<Self>, vm: &VM, idx: usize) -> Result<Val, Box<VMError>>

Return the item at index idx (using SOM indexing starting at 1) or an error if the index is invalid.

unsafe fn unchecked_at(self: Gc<Self>, idx: usize) -> Val

Return the item at index idx (using SOM indexing starting at 1). This will lead to undefined behaviour if the index is invalid.

fn at_put(
    self: Gc<Self>,
    vm: &mut VM,
    idx: usize,
    val: Val
) -> Result<(), Box<VMError>>

Set the item at index idx (using SOM indexing starting at 1) to val or return an error if the index is invalid.

fn iter(self: Gc<Self>) -> ArrayIterator

Iterate over this array’s values.

impl Debug for NormalArray

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

Formats the value using the given formatter.

impl !NoTrace for NormalArray

impl NotUnboxable for NormalArray

impl Obj for NormalArray

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_array(self: Gc<Self>) -> Result<Gc<dyn Array>, Box<VMError>>

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

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

What is this object’s hashcode?

fn length(self: Gc<Self>) -> usize

What is this object’s length?

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

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

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