pub fn data_name_of(file: &str, n_files: usize) -> Result<Option<Box<str>>>Expand description
The data_name SparseIoVec::push takes for a backend read from
file, one of n_files stacked side by side
(ColumnAlignment::Disjoint): the file’s stem (a/pbmc.zarr.zip →
pbmc) when there are several, so cells sharing a barcode across files
stay apart, and none for a single file. read_data_on_shared_rows and
the CLI’s readers name cells by this rule.
