Enum AllocTime 

pub enum AllocTime {
    Early,
    Late,
    Incr,
}

When a dataset’s raw-data storage is allocated — H5Pset_alloc_time/H5Pget_alloc_time’s H5D_alloc_time_t, read back from the same fill-value message FillTime is.

H5P__set_layout (H5Pdcpl.c) picks this from the dataset’s storage class (H5D_ALLOC_TIME_DEFAULT per layout — compact is Early, chunked and virtual are Incr, contiguous is Late). The one override this crate’s builder offers is DatasetBuilder::early_allocation, which a chunked dataset reads back as Early where the writer took it up: an implicit index, or a single unfiltered chunk. H5Dataset::alloc_time reads back what the writer declared.

Variants

Early

Space is allocated as soon as the dataset is created.

Late

Space is allocated when data is first written.

Incr

Space is allocated incrementally, as chunks (or virtual source datasets) are written.
