Enum darling::util::Shape

source · [−]

pub enum Shape {
    Named,
    Tuple,
    Unit,
    Newtype,
}

Expand description

Description of how fields in a struct or variant are syntactically laid out.

Variants

`Named`

A set of named fields, e.g. { field: String }.

`Tuple`

A list of unnamed fields, e.g. (String, u64).

`Unit`

No fields, e.g. struct Example;

`Newtype`

A special case of Tuple with exactly one field, e.g. (String).
