sourcepub unsafe fn new(int_type: LLVMTypeRef) -> Self
pub unsafe fn new(int_type: LLVMTypeRef) -> Self
sourcepub fn const_int(self, value: u64, sign_extend: bool) -> IntValue<'ctx>
pub fn const_int(self, value: u64, sign_extend: bool) -> IntValue<'ctx>
Creates an IntValue
representing 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();

sourcepub fn const_int_from_string(

radix: StringRadix
) -> Option<IntValue<'ctx>>
pub fn const_int_from_string( self, slice: &str, radix: StringRadix ) -> Option<IntValue<'ctx>>

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.
