Trait std::os::wasi::fs::FileTypeExt

pub trait FileTypeExt {
    fn is_block_device(&self) -> bool;
    fn is_character_device(&self) -> bool;
    fn is_socket_dgram(&self) -> bool;
    fn is_socket_stream(&self) -> bool;
}

🔬 This is a nightly-only experimental API. (wasi_ext #71213)

This is supported on WASI only.

fs::FileType 的 WASI 特定扩展。

增加了对特殊 WASI 文件类型的支持，例如 block/character 设备，管道和套接字。

Required methods

fn is_block_device(&self) -> bool

🔬 This is a nightly-only experimental API. (wasi_ext #71213)

fn is_character_device(&self) -> bool

🔬 This is a nightly-only experimental API. (wasi_ext #71213)

如果此文件类型是字符设备，则返回 true。

fn is_socket_dgram(&self) -> bool

🔬 This is a nightly-only experimental API. (wasi_ext #71213)

如果此文件类型是套接字数据报，则返回 true。

fn is_socket_stream(&self) -> bool

🔬 This is a nightly-only experimental API. (wasi_ext #71213)

如果此文件类型是套接字流，则返回 true。
