std::os::unix::fs::FileTypeExt - Rust
Description: API documentation for the Rust `FileTypeExt` trait in crate `std`.
Keywords: rust, rustlang, rust-lang, FileTypeExt

# Trait std::os::unix::fs::FileTypeExt 1.5.0 [−] [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;
    }

This is supported on Unix only.

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

## Required Methods

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

This is supported on Unix only.

Returns whether this file type is a block device.

# Examples

    use std::fs;
    use std::os::unix::fs::FileTypeExt;

    let meta = fs::metadata("block_device_file")?;
    let file_type = meta.file_type();
    assert!(file_type.is_block_device());Run

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

This is supported on Unix only.

Returns whether this file type is a char device.

# Examples

    use std::fs;
    use std::os::unix::fs::FileTypeExt;

    let meta = fs::metadata("char_device_file")?;
    let file_type = meta.file_type();
    assert!(file_type.is_char_device());Run

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

This is supported on Unix only.

Returns whether this file type is a fifo.

# Examples

    use std::fs;
    use std::os::unix::fs::FileTypeExt;

    let meta = fs::metadata("fifo_file")?;
    let file_type = meta.file_type();
    assert!(file_type.is_fifo());Run

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

This is supported on Unix only.

Returns whether this file type is a socket.

# Examples

    use std::fs;
    use std::os::unix::fs::FileTypeExt;

    let meta = fs::metadata("unix.socket")?;
    let file_type = meta.file_type();
    assert!(file_type.is_socket());Run

## 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`)
