Module ark_relations::r1cs
source · Expand description
Core interface for working with Rank-1 Constraint Systems (R1CS).
Macros
Constructs a span at the info level.
Structs
The A, B and C matrices of a Rank-One
ConstraintSystem
.
Also contains metadata on the structure of the constraint system
and the matrices.An Rank-One
ConstraintSystem
. Enforces constraints of the form
⟨a_i, z⟩ ⋅ ⟨b_i, z⟩ = ⟨c_i, z⟩
, where a_i
, b_i
, and c_i
are linear
combinations over variables, and z
is the concrete assignment to these
variables.An opaque counter for symbolic linear combinations.
A linear combination of variables according to associated coefficients.
A namespaced
ConstraintSystemRef
.Enums
A shared reference to a constraint system that can be stored in high level
variables.
Defines the parameter to optimize for a
ConstraintSystem
.This is an error that could occur during circuit synthesis contexts,
such as CRS generation, proving or verification.
Defines the mode of operation of a
ConstraintSystem
.Represents the different kinds of variables present in a constraint system.
Traits
Computations are expressed in terms of rank-1 constraint systems (R1CS).
The
generate_constraints
method is called to generate constraints for
both CRS generation and for proving.The interface for a generic field.
Types implementing
Types implementing
Field
support common field operations such as addition, subtraction, multiplication, and inverses.Types that can be converted to a vector of
F
elements. Useful for
specifying how public inputs to a constraint system should be represented
inside that constraint system.
