Create a draw controller for one simulation

Usage

sim_draws(
  mode = c("rng", "replay"),
  seed = NULL,
  record = NULL,
  tol_rel = 1e-06,
  tol_abs = 1e-09
)

mode: Either "rng" (draw from R's generator) or "replay" (pop recorded draws from record and assert they match).
seed: Integer seed. Used in "rng" mode.
record: Replay record from sim_read_fixture(). Required when mode = "replay".
tol_rel, tol_abs: Combined tolerance for comparing draw parameters against the record: abs(a - b) <= tol_abs + tol_rel * abs(b). A purely relative tolerance is wrong here because rates legitimately reach exactly zero in low-transmission patches.

A draw controller (an environment).
