Detailed Description

Class to represent struct types.

There are two different kinds of struct types: Literal structs and Identified structs.

Literal struct types (e.g. { i32, i32 }) are uniqued structurally, and must always have a body when created. You can get one of these by using one of the StructType::get() forms.

Identified structs (e.g. foo or %42) may optionally have a name and are not uniqued. The names for identified structs are managed at the LLVMContext level, so there can only be a single identified struct with a given name in a particular LLVMContext. Identified structs may also optionally be opaque (have no body specified). You get one of these by using one of the StructType::create() forms.

Independent of what kind of struct you have, the body of a struct type are laid out in memory consecutively with the elements directly one after the other (if the struct is packed) or (if not packed) with padding between the elements as defined by DataLayout (which is required to match what the code generator for a target expects).
