Default Thread Count — fast_default

Returns the default thread count used by fastRanges overlap routines.

Usage

fast_default_threads()

Value

Integer scalar thread count.

Details

The default is controlled by getOption("fastRanges.threads") and falls back to 1L.

This helper is mainly useful when you want package-wide thread control without passing threads = to every call.

Example:

options(fastRanges.threads = 8L) sets the default thread count for later calls that do not specify threads explicitly.

Examples

fast_default_threads()
#> [1] 1
old_threads <- getOption("fastRanges.threads")
options(fastRanges.threads = 3L)
fast_default_threads()
#> [1] 3
options(fastRanges.threads = old_threads)
