Struct CountersHeader 

Source 
pub struct CountersHeader {
    pub magic: u32,
    pub version: u32,
    pub slot_count: AtomicU32,
    pub slot_capacity: u32,
    pub slot_stride: u32,
    pub slots_offset: u32,
    /* private fields */
}
Expand description

Header for the counters file region. Lives at the start of the reserved zone described in RFC 0040.

Fields§

§magic: u32

COUNTERS_MAGIC when valid.

§version: u32

Layout version; bumped when slot stride or header shape changes.

§slot_count: AtomicU32

Number of slots actually in use; advances monotonically.

§slot_capacity: u32

Maximum slots the array can hold (always MAX_COUNTER_SLOTS).

§slot_stride: u32

Bytes per slot (size_of::<CounterSlot>()); included so external readers don’t need to depend on this crate’s structs.

§slots_offset: u32

Bytes from the start of this header to the first slot.
