Struct snarkvm_r1cs::LinearCombination[−][src]

pub struct LinearCombination<F: Field>(pub Vec<(Variable, F)>);
Expand description

This represents a linear combination of some variables, with coefficients in the field F. The (coeff, var) pairs in a LinearCombination are kept sorted according to the index of the variable in its constraint system.
