Enum shades::scope::ScopedHandle

pub enum ScopedHandle {
    BuiltIn(BuiltIn),
    Global(u16),
    FunArg(u16),
    FunVar {
        subscope: u16,
        handle: u16,
    },
    Input(u16),
    Output(u16),
    Env(String),
}

Hierarchical and namespaced handle.

Handles live in different namespaces:

• The built-in namespace gathers all built-ins.
• The global namespace gathers everything that can be declared at top-level of a shader stage — i.e. mainly constants for this namespace.
• The input namespace gathers inputs.
• The output namespace gathers outputs.
• The function argument namespace gives handles to function arguments, which exist only in a function body.
• The function variable namespace gives handles to variables defined in function bodies. This namespace is hierarchical: for each scope, a new namespace is created. The depth at which a namespace is located is referred to as its subscope.
