Implementations§

source§

impl<'ctx> StructValue<'ctx>

source

pub unsafe fn new(value: LLVMValueRef) -> Self

Get a value from an LLVMValueRef.

§Safety

The ref must be valid and of type struct.

source

pub fn get_field_at_index(self, index: u32) -> Option<BasicValueEnum<'ctx>>

Gets the value of a field belonging to this StructValue.

use inkwell::context::Context;

let context = Context::create();
let i32_type = context.i32_type();
let i8_type = context.i8_type();
let i8_val = i8_type.const_all_ones();
let i32_val = i32_type.const_all_ones();
let struct_type = context.struct_type(&[i8_type.into(), i32_type.into()], false);
let struct_val = struct_type.const_named_struct(&[i8_val.into(), i32_val.into()]);

assert!(struct_val.get_field_at_index(0).is_some());
assert!(struct_val.get_field_at_index(1).is_some());
assert!(struct_val.get_field_at_index(3).is_none());
assert!(struct_val.get_field_at_index(0).unwrap().is_int_value());
source

pub unsafe fn get_field_at_index_unchecked( self, index: u32 ) -> BasicValueEnum<'ctx>

Gets the value of a field belonging to this StructValue.

§Safety

The index must be smaller than StructValue::count_fields.

source

pub fn get_fields(self) -> FieldValueIter<'ctx>

Get a field value iterator.

source

pub fn set_field_at_index<BV: BasicValue<'ctx>>( self, index: u32, val: BV ) -> bool

Sets the value of a field belonging to this StructValue.

source

pub fn count_fields(self) -> u32

Counts the number of fields.

use inkwell::context::Context;

let context = Context::create();
let i32_type = context.i32_type();
let i8_type = context.i8_type();
let i8_val = i8_type.const_all_ones();
let i32_val = i32_type.const_all_ones();
let struct_type = context.struct_type(&[i8_type.into(), i32_type.into()], false);
let struct_val = struct_type.const_named_struct(&[i8_val.into(), i32_val.into()]);

assert_eq!(struct_val.count_fields(), 2);
assert_eq!(struct_val.count_fields(), struct_type.count_fields());
