Struct ObjectTimes 

pub struct ObjectTimes {
    pub access: u32,
    pub modification: u32,
    pub change: u32,
    pub birth: u32,
}

The four times a version-2 object header stores, in the order H5O__cache_serialize writes them: seconds since the epoch, as H5_now produces them.

Their presence is the H5O_HDR_STORE_TIMES flag — see ObjectHeader::times — so an object created with H5Pset_obj_track_times(true) cannot be encoded with the flag set and no times behind it.

Fields

access: u32

Access time (oh->atime).

modification: u32

Modification time (oh->mtime).

change: u32

Change time (oh->ctime).

birth: u32

Birth time (oh->btime).

Implementations

impl ObjectTimes

pub fn created_at(now: u32) -> Self

All four set to now — what H5O_create_ohdr does for an object created with timestamps enabled.

pub fn touched(self, now: u32) -> Self

These times after a real modification of the object.

H5O_touch_oh moves access and change time to now for a version-2 header and leaves modification and birth time as they were — the modification time is what its own XXX comment says is not updated yet. Following it means a rewrite reports the same times libhdf5 would.
