Function const_struct

Source 
pub fn const_struct(constant_vals: &[ValueRef], packed: bool) -> ValueRef
Expand description

Create a ConstantStruct in the global Context.

This is the same as constStruct_in_context except it operates on the global context.

§Details

Creates a constant struct value in the global LLVM context.

This function wraps the LLVMConstStruct function from the LLVM core library. It generates a constant struct value using an array of constant values (constant_vals). The packed parameter allows you to specify whether the struct should be packed, meaning that its fields are laid out without padding. This function operates in the global LLVM context, as opposed to a specific context.

§Parameters

  • constant_vals: A slice of constant values &ValueRef that will be used as the fields of the struct. Each element in this slice corresponds to a field in the struct.
  • packed: A boolean value indicating whether the struct should be packed (true for packed, false for unpacked). A packed struct has its fields tightly packed without padding.

§Returns

Returns an instance of ValueRef, which encapsulates the constant struct value created in the global context.
