Struct for containing:

RustCycleCache

RustCycleElement

Functions

accel_array_for_constant_jerk

Apply accel_for_constant_jerk to full

accel_for_constant_jerk

Calculate the acceleration n timesteps away

average_step_speed_at

Calculate the average step speed at step i in m/s (i.e., from sample point i-1 to i)

average_step_speeds

Calculate the average speed per each step in m/s

calc_constant_jerk_trajectory

Arguments

create_dist_and_target_speeds_by_microtrip

Create distance and target speeds by microtrip This helper function splits a cycle up into microtrips and returns a list of 2-tuples of: (distance from start in meters, target speed in meters/second)

detect_passing

Reports back information of the first point where cyc passes cyc0, starting at step i until the next stop of cyc.

dist_for_constant_jerk

Calculate distance (m) after n timesteps

extend_cycle

cyc: fastsim.cycle.Cycleabsolute_time_s: float, the seconds to extendtime_fraction: float, the fraction of the original cycle time to add onuse_rust: bool, if True, return a RustCycle instance, else a normal Python Cycle RETURNS: fastsim.cycle.Cycle (or fastsimrust.RustCycle), the new cycle with stopped time appended NOTE: additional time is rounded to the nearest second

speed_for_constant_jerk

Calculate speed (m/s) n timesteps away via a constant-jerk acceleration

time_spent_moving

Calculate the time in a cycle spent moving

to_microtrips

Split a cycle into an array of microtrips with one microtrip being a start to subsequent stop plus any idle (stopped time). Arguments:

trapz_distance_for_step

The distance traveled during step i in meters (i.e., from sample point i-1 to i)

trapz_distance_over_range

Calculate the distance from step i_start to the start of step i_end (i.e., distance from sample point i_start-1 to i_end-1)

trapz_step_distances

Sum of the distance traveled over each step using trapezoidal integration

trapz_step_distances_primitive

trapz_step_start_distance

The distance traveled from start at the beginning of step i (i.e., distance traveled up to sample point i-1) Distance is in meters.
