Function const_bit_cast

Source 
pub fn const_bit_cast(val: &ValueRef, to_type: &TypeRef) -> ValueRef
Expand description

Perform a bitcast operation on a constant value to the specified type.

§Details

Performs a constant bitcast of a value to another type without changing the bit representation.

This function wraps the LLVMConstBitCast function from the LLVM core library. It generates a constant bitcast instruction, which reinterprets the value represented by ValueRef as another type specified by to_type. The bitcast does not change the underlying bit representation of the value; it merely reinterprets it as a different type. This is typically used for converting between types of the same size, such as casting between integers and pointers or between different floating-point types.

§Parameters

  • to_type: A reference to the target type (TypeRef) to which the value should be cast. This type must have the same bit width as the original type.

§Returns

Returns an instance of ValueRef, which encapsulates the result of the bitcast. The result is a constant value determined at compile time, representing the value reinterpreted as the target type.
