Function const_null

pub fn const_null(ty: &TypeRef) -> ValueRef

Obtain a constant value referring to the null instance of a type.

Details

Creates a constant ‘null’ value of the specified type.

This function wraps the LLVMConstNull function from the LLVM core library. It generates a constant ‘null’ value for the specified type (ty). This is typically used for pointer types, where the null value represents a pointer to no valid memory location, but it can also be used for other types where a zero-initialized constant is required.

Parameters

• ty: A reference to the type (TypeRef) for which the null value should be created. This type determines the kind of null value that is generated (e.g., null pointer, zero-initialized struct).

Returns

Returns an instance of ValueRef, which encapsulates the constant null value for the specified type.
