[][src]Enum mio_aio::BufRef

pub enum BufRef {
    None,
    BoxedSlice(Box<dyn Borrow<[u8]>>),
    BoxedMutSlice(Box<dyn BorrowMut<[u8]>>),
}

Stores a reference to the buffer used by the AioCb, if any.

After the I/O operation is done, can be retrieved by buf_ref

Variants

None

Either the AioCb has no buffer, as for an fsync operation, or a reference can't be stored, as when constructed from a slice

BoxedSlice(Box<dyn Borrow<[u8]>>)

Immutable generic boxed slice

BoxedMutSlice(Box<dyn BorrowMut<[u8]>>)

Mutable generic boxed slice

Methods

impl BufRef[src]

pub fn boxed_slice(&self) -> Option<&dyn Borrow<[u8]>>[src]

Return the inner BoxedSlice, if any

pub fn boxed_mut_slice(&mut self) -> Option<&mut dyn BorrowMut<[u8]>>[src]

Return the inner BoxedMutSlice, if any

pub fn is_none(&self) -> bool[src]

Is this BufRef None?

pub fn len(&self) -> Option<usize>[src]

Length of the buffer, if any
