Struct ring_buf 

#[repr(C)]
pub struct ring_buf {
    pub buffer: *mut u8,
    pub size: u16,
    pub read_idx: u16,
    pub write_idx: u16,
}

@brief A structure to represent a ring buffer.

The struct stores the buffer capacity @p size (N). No slot is sacrificed: @p read_idx and @p write_idx are free-running indices in [0, 2N), so the full and empty states are disambiguated by their lap rather than by a reserved slot. The user-visible capacity equals @p size.

Fields

buffer: *mut u8

@cond INTERNAL_HIDDEN

size: u16

read_idx: u16

write_idx: u16
