Implementations§

source§

impl<'ctx> FloatValue<'ctx>

source

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

Get a value from an LLVMValueRef.

Safety

The ref must be valid and of type float.

source

pub fn get_name(&self) -> &CStr

Gets name of the FloatValue. If the value is a constant, this will return an empty string.

source

pub fn set_name(&self, name: &str)

Set name of the FloatValue.

source

pub fn get_type(self) -> FloatType<'ctx>

source

pub fn is_null(self) -> bool

source

pub fn is_undef(self) -> bool

source

pub fn print_to_stderr(self)

source

pub fn as_instruction(self) -> Option<InstructionValue<'ctx>>

source

pub fn const_cast(self, float_type: FloatType<'ctx>) -> Self

source

pub fn const_to_unsigned_int(self, int_type: IntType<'ctx>) -> IntValue<'ctx>

source

pub fn const_to_signed_int(self, int_type: IntType<'ctx>) -> IntValue<'ctx>

source

pub fn const_truncate(self, float_type: FloatType<'ctx>) -> FloatValue<'ctx>

source

pub fn const_extend(self, float_type: FloatType<'ctx>) -> FloatValue<'ctx>

source

pub fn const_compare( self, op: FloatPredicate, rhs: FloatValue<'ctx> ) -> IntValue<'ctx>

source

pub fn is_const(self) -> bool

Determines whether or not a FloatValue is a constant.

Example
use inkwell::context::Context;

let context = Context::create();
let f64_type = context.f64_type();
let f64_val = f64_type.const_float(1.2);

assert!(f64_val.is_const());
source

pub fn get_constant(self) -> Option<(f64, bool)>

Obtains a constant FloatValue’s value and whether or not it lost info.

Example
use inkwell::context::Context;

let context = Context::create();
let f64_type = context.f64_type();
let f64_1_2 = f64_type.const_float(1.2);

assert_eq!(f64_1_2.get_constant(), Some((1.2, false)));
source
