Write one cached slot to disk (crash-safe via atomic rename)

Writes object to an RDS file inside cache_dir/slot_name/ using an atomic rename pattern (write to a .rds.tmp file, then file.rename() to the final .rds). When the filelock package is installed, a shared file lock is held during the rename to prevent concurrent writes from clobbering each other.

Usage

.tdr_cache_write(object, cache_dir, slot_name, sample_name, compress = FALSE)

Arguments

object

R object to serialize.

cache_dir

Root cache directory for the current run.

slot_name

Character – one of "clustering", "celltyping", "nearest.lm", "fuzzy.graphs".

sample_name

Character – sample identifier (used as file stem).

compress

Passed to saveRDS. Default FALSE for speed.

Value

An attributed path string: a character scalar with attr(, "schema_v") and attr(, "bytes") set.
