Trait ark_r1cs_std::bits::ToBitsGadget

pub trait ToBitsGadget<F: Field> {
    fn to_bits_le(&self) -> Result<Vec<Boolean<F>>, SynthesisError>;

    fn to_non_unique_bits_le(&self) -> Result<Vec<Boolean<F>>, SynthesisError> { ... }
    fn to_bits_be(&self) -> Result<Vec<Boolean<F>>, SynthesisError> { ... }
    fn to_non_unique_bits_be(&self) -> Result<Vec<Boolean<F>>, SynthesisError> { ... }
}

Specifies constraints for conversion to a little-endian bit representation of self.

Required Methods

fn to_bits_le(&self) -> Result<Vec<Boolean<F>>, SynthesisError>

Outputs the canonical little-endian bit-wise representation of self.

This is the correct default for 99% of use cases.

Provided Methods

fn to_non_unique_bits_le(&self) -> Result<Vec<Boolean<F>>, SynthesisError>

Outputs a possibly non-unique little-endian bit-wise representation of self.

If you’re not absolutely certain that your usecase can get away with a non-canonical representation, please use self.to_bits() instead.

fn to_bits_be(&self) -> Result<Vec<Boolean<F>>, SynthesisError>

Outputs the canonical big-endian bit-wise representation of self.

fn to_non_unique_bits_be(&self) -> Result<Vec<Boolean<F>>, SynthesisError>

Outputs a possibly non-unique big-endian bit-wise representation of self.
