Enum File

pub enum File {
    Tokio(File),
    Uring(File),
}

An adapter enum to support both tokio and tokio-uring asynchronous File.

Variants

Tokio(File)

Tokio asynchronous File.

Uring(File)

Tokio-uring asynchronous File.

Implementations

impl File

pub async fn async_open<P: AsRef<Path>>( path: P, write: bool, create: bool, ) -> Result<Self>

Asynchronously open a file.

pub async fn async_read_at( &self, buf: FileVolatileBuf, offset: u64, ) -> (Result<usize>, FileVolatileBuf)

Asynchronously read data at offset into the buffer.

pub async fn async_readv_at( &self, bufs: Vec<FileVolatileBuf>, offset: u64, ) -> (Result<usize>, Vec<FileVolatileBuf>)

Asynchronously read data at offset into buffers.

pub async fn async_write_at( &self, buf: FileVolatileBuf, offset: u64, ) -> (Result<usize>, FileVolatileBuf)

Asynchronously write data at offset from the buffer.

pub async fn async_writev_at( &self, bufs: Vec<FileVolatileBuf>, offset: u64, ) -> (Result<usize>, Vec<FileVolatileBuf>)

Asynchronously write data at offset from buffers.

pub fn metadata(&self) -> Result<Metadata>

Get metadata about the file.

pub async fn async_try_clone(&self) -> Result<Self>

Try to clone the file object.
