Module `Vernacstate.Stm`

STM-specific state handling

type pstate: Proof state + meta/evar counters

val pstate : t -> pstate
val set_pstate : t -> pstate -> t

type non_pstate = Summary.Synterp.frozen * Lib.Synterp.frozen * Summary.Interp.frozen * Lib.Interp.frozen: Rest of the state, unfortunately this is used in low-level so we need to expose it

val non_pstate : t -> non_pstate
val same_env : t -> t -> bool: Checks if two states have the same Environ.env (physical eq)

val make_shallow : t -> t: Call Lib.drop_objects on the state
