assert_eq!(i8_array_array_type.get_element_type().into_array_type(), i8_array_type);

pub fn const_array(self, values: &[ArrayValue<'ctx>]) -> ArrayValue<'ctx>

Creates a constant ArrayValue.

Example

use inkwell::context::Context;

let context = Context::create();
let f32_type = context.f32_type();
let f32_array_type = f32_type.array_type(3);
let f32_array_val = f32_array_type.const_zero();
let f32_array_array = f32_array_type.const_array(&[f32_array_val, f32_array_val]);

assert!(f32_array_array.is_const());

pub fn const_zero(self) -> ArrayValue<'ctx>
