# [−][src]Trait proc_macro::MultiSpan

    pub trait MultiSpan {
        fn into_spans(self) -> Vec<Span>;
    }

🔬 This is a nightly-only experimental API. (`proc_macro_diagnostic` #54140)

Trait implemented by types that can be converted into a set of `Span`s.

## Required methods

### `fn into_spans(self) -> Vec<Span>`

🔬 This is a nightly-only experimental API. (`proc_macro_diagnostic` #54140)

Converts `self` into a `Vec<Span>`.

## 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`)
