Input of type 'a to a Plompiler program. These hold a value of type 'a with some additional structure used for constructing the circuit. Often, after implementing a Plompiler program, one is left with a function of the shape:

val prog : 'a input -> 'b input -> unit repr t.

If the user only wants to execute the program in order to compute the corresponding circuit, but without producing a proof, then the inputs can be set to dummy values, as they will be ignored. That is, only the structure of the input is used for building the circuit.

scalar s describes a scalar input holding the value s.

to_scalar i retrieves the value from a scalar input.

bool b describes a boolean input holding the value b.

to_bool i retrieves the value from a boolean input.

unit describes a unit input.

pair a b describes the input tuple (a, b) made out of inputs a and b.

to_pair p retrieves the inputs (a, b) that make up the input tuple p.

list l turns a list of inputs l into an list input.

to_list li turns a list input li into a list of inputs.

with_implicit_bool_check bc i attaches an implicit bool check bc to the input i.

with_assertion assrtn i attaches an assertion assrtn to the input i.
