fn is_32bit() bool
is_32bit returns true if the current executable is running on a 32 bit system.
fn is_64bit() bool
is_64bit returns true if the current executable is running on a 64 bit system.
fn is_big_endian() bool
is_big_endian returns true if the current executable is running on a big-endian system.
fn is_little_endian() bool
is_little_endian returns true if the current executable is running on a little-endian system.
fn nr_cpus() int
nr_cpus returns the number of virtual CPU cores found on the system.
fn nr_jobs() int
nr_jobs returns the same as nr_cpus
with the difference that if an environment variable VJOBS
is set, and has a value > 0, then nr_jobs
will return that number instead. This is useful for runtime tweaking of e.g. threaded or concurrent code.
