Trait HasCursor

pub trait HasCursor {
    type Cursor<'a>: Read + 'a
       where Self: 'a;

    // Required method
    fn cursor_at(&self, offset: u64) -> Self::Cursor<'_>;
}

A sliceable I/O resource: we can ask for a Read at a given offset.

Required Associated Types

type Cursor<'a>: Read + 'a where Self: 'a

The type of Read returned by HasCursor::cursor_at.

Required Methods

fn cursor_at(&self, offset: u64) -> Self::Cursor<'_>

Returns a Read at the given offset.

Object Safety

This trait is not object safe.
