# Struct aho_corasick::AcAutomaton [−] [src]

    pub struct AcAutomaton<P, T = Dense> {
        // some fields omitted
    }

An Aho-Corasick finite automaton.

The type parameter `P` is the type of the pattern that was used to construct this AcAutomaton.

## Methods

### `impl<P: AsRef<[u8]>> AcAutomaton<P>`

#### `fn new<I>(pats: I) -> AcAutomaton<P, Dense> where I: IntoIterator<Item=P>`

Create a new automaton from an iterator of patterns.

The patterns must be convertible to bytes (`&[u8]`) via the `AsRef` trait.

### `impl<P: AsRef<[u8]>, T: Transitions> AcAutomaton<P, T>`

#### `fn with_transitions<I>(pats: I) -> AcAutomaton<P, T> where I: IntoIterator<Item=P>`

Create a new automaton from an iterator of patterns.

This constructor allows one to choose the transition representation.

The patterns must be convertible to bytes (`&[u8]`) via the `AsRef` trait.

#### `fn into_full(self) -> FullAcAutomaton<P>`

Build out the entire automaton into a single matrix.

This will make searching as fast as possible at the expense of using at least `4 * 256 * #states` bytes of memory.

## 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`)
