# Enum std::str::pattern::SearchStep [−] [src]

    pub enum SearchStep {
        Match(usize, usize),
        Reject(usize, usize),
        Done,
    }

Unstable (`pattern` #27721)

: API not fully fleshed out and ready to be stabilized

Result of calling `Searcher::next()` or `ReverseSearcher::next_back()`.

## Variants

`Match` | Unstable (`pattern` #27721) : API not fully fleshed out and ready to be stabilized Expresses that a match of the pattern has been found at `haystack[a..b]`. |
`Reject` | Unstable (`pattern` #27721) : API not fully fleshed out and ready to be stabilized Expresses that `haystack[a..b]` has been rejected as a possible match of the pattern. Note that there might be more than one `Reject` between two `Match`es, there is no requirement for them to be combined into one. |
`Done` | Unstable (`pattern` #27721) : API not fully fleshed out and ready to be stabilized Expresses that every byte of the haystack has been visted, ending the iteration. |

## 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`)
