Struct BufferElement 

pub struct BufferElement {
    pub addr: u64,
    pub len: u32,
    pub writable: bool,
}

A single buffer element in a scatter-gather list.

Represents one contiguous memory region that the device will read from or write to. Multiple elements can be chained together to form a BufferChain.

Fields

addr: u64

Physical address of buffer

len: u32

Length of the buffer in bytes

writable: bool

Whether this buffer is writable by the device
