True iff not private

Sourceval same_mutability : fun_mutability -> fun_mutability -> bool

Checks the equality of mutabilities

Sourceval convertible_mutability : from:fun_mutability -> to_:fun_mutability -> bool

Tests if a function with `from` mutability can be overridden by a function with `to` mutability.

Sourceval same_visibility : visibility -> visibility -> bool

Checks the equality of visibilities

Sourceval convertible_visibility : from:visibility -> to_:visibility -> bool

Tests if a function with `from` visibility can be overridden by a function with `to` visibility.

Sourceval apply_unit : Q.t -> number_unit -> Q.t

Returns the quantity in argument with the unit in argument in the smallest quantity of the language of the similar unit. Examples: * `apply_unit 1 Minutes = 60 (Seconds)` * `apply_unit 1 Ether = 1e15 (Wei)` * `apply_unit 1 Unit = 1 (Unit)`

Sourceval apply_unop : unary_operator -> Q.t -> Q.t option

Apply the unary operator in argument to a zarith rational. Returns `None` when applying UNot on non-integers If the operator is not an arithmetical operator, also returns `None`.

Sourceval apply_binop : Q.t -> binary_operator -> Q.t -> Q.t option

Apply the binary operator in argument to a zarith rational. If the operator is not an arithmetical operator, returns `None`.
