# Trait std::os::unix::fs::FileTypeExt [−] [src]

    pub trait FileTypeExt {
        fn is_block_device(&self) -> bool;
        fn is_char_device(&self) -> bool;
        fn is_fifo(&self) -> bool;
        fn is_socket(&self) -> bool;
    }

Add special unix types (block/char device, fifo and socket)

## Required Methods

### `fn is_block_device(&self) -> bool`

Returns whether this file type is a block device.

### `fn is_char_device(&self) -> bool`

Returns whether this file type is a char device.

### `fn is_fifo(&self) -> bool`

Returns whether this file type is a fifo.

### `fn is_socket(&self) -> bool`

Returns whether this file type is a socket.

## 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`)
