proc_macro::Spacing - Rust
Description: API documentation for the Rust `Spacing` enum in crate `proc_macro`.
Keywords: rust, rustlang, rust-lang, Spacing

# Enum proc_macro::Spacing 1.29.0[−][src]

    pub enum Spacing {
        Alone,
        Joint,
    }

Whether an `Punct` is followed immediately by another `Punct` or followed by another token or whitespace.

## Variants

`Alone`

E.g. `+` is `Alone` in `+ =`, `+ident` or `+()`.

`Joint`

E.g. `+` is `Joint` in `+=` or `'#`. Additionally, single quote `'` can join with identifiers to form lifetimes `'ident`.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
