TimeLimit

class PlasmaCalcs.tools.timing.TimeLimit(seconds)

Bases: object

context manager which imposes a time limit, exiting with TimeoutError if internal code takes too long.

Usage example:

with TimeLimit(10):

# any code in this block must complete within 10 seconds, else will crash with TimeoutError.

seconds: None or int

timeout after this many seconds (unless code completes before then).

Must be an integer, due to limitations of signal.alarm method.

None, or <=0 –> no time limit

Methods

now	time() -> floating point number
signal_handler(_signum, _frame)	raise TimeoutError.
time_elapsed()	returns time elapsed since entering the context.

static now()

time() -> floating point number

Return the current time in seconds since the Epoch.

Fractions of a second may be present if the system clock provides them.

signal_handler(_signum, _frame)

raise TimeoutError.

time_elapsed()

returns time elapsed since entering the context.
