Enum proc_macro::Spacing

1.29.0 · source · [−]

pub enum Spacing {
    Alone,
    Joint,
}

Expand description

Describes whether a Punct is followed immediately by another Punct (Spacing::Joint) or by a different token or whitespace (Spacing::Alone).

Variants

`Alone`

A Punct is not immediately followed by another Punct. E.g. + is Alone in + =, +ident and +().

`Joint`

A Punct is immediately followed by another Punct. E.g. + is Joint in += and ++.

Additionally, single quote ' can join with identifiers to form lifetimes: 'ident.
