Trait DynRead

pub unsafe trait DynRead:
    MaybeSend
    + MaybeSync
    + Sealed {
    // Required methods
    fn read_exact_at(
        &mut self,
        buf: BufMut,
        pos: u64,
    ) -> Pin<Box<dyn MaybeSendFuture<Output = (Result<(), Error>, BufMut)> + '_>>;
    fn read_to_end_at(

}

Available on crate feature alloc only.

Dyn compatible (object safe) version of Read.

Similar to DynWrite, all implementations of Read automatically implement this trait. Users should not use this trait directly.

Safety

Do not implement this trait directly. All implementations of Read automatically implement this trait.

Required Methods

fn read_exact_at( &mut self, buf: BufMut, pos: u64, ) -> Pin<Box<dyn MaybeSendFuture<Output = (Result<(), Error>, BufMut)> + '_>>

fn read_to_end_at( &mut self, buf: Vec<u8>, pos: u64, ) -> Pin<Box<dyn MaybeSendFuture<Output = (Result<(), Error>, Vec<u8>)> + '_>>

fn size( &self, ) -> Pin<Box<dyn MaybeSendFuture<Output = Result<u64, Error>> + '_>>
