Struct inkwell::types::IntType[][src]

pub struct IntType<'ctx> { /* fields omitted */ }
Expand description

An IntType is the type of an integer constant or variable.

Implementations

Creates an IntValue repesenting a constant value of this IntType. It will be automatically assigned this IntType’s Context.

Example

use inkwell::context::Context;

// Local Context
let context = Context::create();
let i32_type = context.i32_type();
let i32_value = i32_type.const_int(42, false);

Create an IntValue from a string and radix. LLVM provides no error handling here, so this may produce unexpected results and should not be relied upon for validation.

Example

use std::convert::TryFrom;

use inkwell::context::Context;
use inkwell::types::StringRadix;
use inkwell::values::AnyValue;

let context = Context::create();
let i8_type = context.i8_type();
let i8_val = i8_type.const_int_from_string("0121", StringRadix::Decimal).unwrap();

assert_eq!(i8_val.print_to_string().to_string(), "i8 121");

let i8_val = i8_type.const_int_from_string("0121", StringRadix::try_from(10).unwrap()).unwrap();

assert_eq!(i8_val.print_to_string().to_string(), "i8 16");

let i8_val = i8_type.const_int_from_string("0121", StringRadix::Binary);
assert!(i8_val.is_none());

let i8_val = i8_type.const_int_from_string("ABCD", StringRadix::Binary);
assert!(i8_val.is_none());

Create a constant IntValue of arbitrary precision.

Example

use inkwell::context::Context;

let context = Context::create();
let i64_type = context.i64_type();
let i64_val = i64_type.const_int_arbitrary_precision(&[1, 2]);

Creates an IntValue representing a constant value of all one bits of this IntType. It will be automatically assigned this IntType’s Context.

Example

use inkwell::context::Context;

// Local Context
let context = Context::create();
let i32_type = context.i32_type();
let i32_ptr_value = i32_type.const_all_ones();

Creates a constant zero value of this IntType.

Example

use inkwell::context::Context;
use inkwell::values::AnyValue;

let context = Context::create();
let i8_type = context.i8_type();
let i8_zero = i8_type.const_zero();

assert_eq!(i8_zero.print_to_string().to_string(), "i8 0");

Creates a FunctionType with this IntType for its return type.

Example

use inkwell::context::Context;

let context = Context::create();
let i8_type = context.i8_type();
let fn_type = i8_type.fn_type(&[], false);

Creates an ArrayType with this IntType for its element type.

Example

use inkwell::context::Context;

let context = Context::create();
let i8_type = context.i8_type();
let i8_array_type = i8_type.array_type(3);

assert_eq!(i8_array_type.len(), 3);
assert_eq!(i8_array_type.get_element_type().into_int_type(), i8_type);

Creates a VectorType with this IntType for its element type.

Example

use inkwell::context::Context;

let context = Context::create();
let i8_type = context.i8_type();
let i8_vector_type = i8_type.vec_type(3);

assert_eq!(i8_vector_type.get_size(), 3);
assert_eq!(i8_vector_type.get_element_type().into_int_type(), i8_type);

Gets a reference to the Context this IntType was created in.

Example

use inkwell::context::Context;

let context = Context::create();
let i8_type = context.i8_type();

assert_eq!(*i8_type.get_context(), context);

Gets the size of this IntType. Value may vary depending on the target architecture.

Example

use inkwell::context::Context;

let context = Context::create();
let i8_type = context.i8_type();
let i8_type_size = i8_type.size_of();

Gets the alignment of this IntType. Value may vary depending on the target architecture.

Example

use inkwell::context::Context;

let context = Context::create();
let i8_type = context.i8_type();
let i8_type_alignment = i8_type.get_alignment();

Creates a PointerType with this IntType for its element type.

Example

use inkwell::context::Context;
use inkwell::AddressSpace;

let context = Context::create();
let i8_type = context.i8_type();
let i8_ptr_type = i8_type.ptr_type(AddressSpace::Generic);

assert_eq!(i8_ptr_type.get_element_type().into_int_type(), i8_type);

Gets the bit width of an IntType.

Example

use inkwell::context::Context;

let context = Context::create();
let bool_type = context.bool_type();

assert_eq!(bool_type.get_bit_width(), 1);

Creates an undefined instance of an IntType.

Example

use inkwell::context::Context;
use inkwell::AddressSpace;

let context = Context::create();
let i8_type = context.i8_type();
let i8_undef = i8_type.get_undef();

assert!(i8_undef.is_undef());

Creates a GenericValue for use with ExecutionEngines.

Creates a constant ArrayValue.

Example

use inkwell::context::Context;

let context = Context::create();
let i8_type = context.i8_type();
let i8_val = i8_type.const_int(0, false);
let i8_val2 = i8_type.const_int(2, false);
let i8_array = i8_type.const_array(&[i8_val, i8_val2]);

assert!(i8_array.is_const());
