Enum Return 

pub enum Return {
    Infer,
    Int(i128),
    UInt(u128),
    Float(f64),
    String(String),
    Object(Object),
    Expression(Expression),
    Identifier(String),
    Array(Box<[Return]>),
    Unit,
}

The Return enum is used as the return type of both methods and functions. It defines both the type and the value.

Variants

Infer

The ‘Infer’ variant is the same as the _ token in Rust

Int(i128)

A signed integer

UInt(u128)

An unsigned integer

Float(f64)

A floating point value

String(String)

A String

Object(Object)

An Object (created via the SealedObjectType::new_instance method)

Expression(Expression)

An Expression (created via the Expression::try_from::<TokenStream> method)

Identifier(String)

Can be used to indirectly reference another value within the proc macro environment

Array(Box<[Return]>)

An array of Array enum values

Unit

The ‘Unit’ variant is the same as the () token in Rust
