Implementations

impl File

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

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)

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