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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
