Module array 

Array FFI Functions for JIT

Functions for creating and manipulating arrays in JIT-compiled code. All arrays are stored as JitAlloc<JitArray> via jit_box(HK_ARRAY, ...).

Structs

ArrayInfo

Extract array data pointer and length from a NaN-boxed array value.

Functions

create_array_from_elements

Helper: Create a new array from elements

get_array_elements

Helper: Extract elements from a NaN-boxed array (returns a clone as Vec)

jit_array_filled

Create a pre-allocated array filled with a given value. Array.filled(size, value) — equivalent to vec![value; size].

jit_array_first

Get first element of array

jit_array_get

Get element from array by index (supports negative indexing)

jit_array_info

jit_array_last

Get last element of array

jit_array_max

Get maximum element of numeric array

jit_array_min

Get minimum element of numeric array

jit_array_pop

Pop last element from array (returns new array without last element)

jit_array_push

Push multiple values onto array (returns new array)

jit_array_push_elem

Push single element onto array (returns new array with element appended) Used by ArrayPush opcode in list comprehensions

jit_array_push_element

Push a single element onto an array (method call style). Returns new array with element appended. Used by JIT inline path for .push(element).

jit_array_push_local

Push a value into an array in-place, mutating the existing JitArray. Returns the same array bits (the JitAlloc pointer doesn’t move; JitArray handles realloc internally). This is O(1) amortized vs O(n) for jit_array_push_elem which copies all elements. Used by ArrayPushLocal opcode for x = x.push(val) optimization.

jit_array_reserve_local

Ensure array capacity is at least min_capacity elements. Returns original array bits.

jit_array_reverse

Reverse an array, returning a new reversed array. Used by JIT inline path for .reverse().

jit_array_zip

Zip two arrays into array of pairs

jit_hof_array_alloc

Allocate a new empty array with pre-allocated capacity. Returns a NaN-boxed HK_ARRAY. Used by HOF inlining to pre-allocate result arrays.

jit_hof_array_push

Push a single element into an in-place array (used by HOF inlining loops). Mutates the JitArray, returns the same boxed array bits. Identical to jit_array_push_local but with a different name for clarity.

jit_make_range

Create a Range object from start and end values This creates a proper Range object (not an array), used by MakeRange opcode

jit_new_array

Create a new array from values on stack

jit_range

Create a range array [start, start+1, …, end-1]

jit_slice

Slice an array or string
