Struct RegisteredSpan 

pub struct RegisteredSpan {
    pub buffer_index: u32,
    pub offset: u32,
    pub len: u32,
}

Which bytes of one registered buffer an operation reads or writes: bundled into one value so a registered read or write stays under a sane argument count.

A registration is a set of buffers a layer holds for many operations and names by index, as io_uring’s fixed buffers and an IoRing’s registered buffers both do; this says which of them, and which part.

Fields

buffer_index: u32

Which buffer within the registration, as the registering layer numbers them.

offset: u32

The starting byte offset within that buffer.

len: u32

How many bytes to read or write.
