Module opendp::measurements

Various measurement constructors.

The different crate::core::Measurement implementations in this module are accessed by calling the appropriate constructor function. Constructors are named in the form make_xxx(), where xxx indicates what the resulting Measurement does.

Functions

• make_alp_histogram_post_process
  Wrapper Measurement. See post_process.
• make_base_alp
  Measurement to compute a DP projection of bounded sparse data.
• make_base_alp_with_hashers
  Measurement to compute a DP projection of bounded sparse data.
• make_base_discrete_gaussian
  Make a Measurement that adds noise from the discrete_gaussian(scale) distribution to the input.
• make_base_discrete_gaussian_rug
• make_base_discrete_laplace
  Make a Measurement that adds noise from the discrete_laplace(scale) distribution to the input.
• make_base_discrete_laplace_cks20
  Make a Measurement that adds noise from the discrete_laplace(scale) distribution to the input, using an efficient algorithm on rational bignums.
• make_base_discrete_laplace_cks20_rug
  Make a Measurement that adds noise from the discrete_laplace(scale) distribution to the input, directly using bignum types from rug.
• make_base_discrete_laplace_linear
  Make a Measurement that adds noise from the discrete_laplace(scale) distribution to the input, using a linear-time algorithm on finite data types.
• make_base_gaussian
  Make a Measurement that adds noise from the gaussian(scale) distribution to the input.
• make_base_geometricDeprecated
  Deprecated. Use make_base_discrete_laplace instead (more efficient). make_base_discrete_laplace_linear has a similar interface with the optional constant-time bounds.
• make_base_laplace
  Make a Measurement that adds noise from the laplace(scale) distribution to a scalar value.
• make_base_ptr
  Make a Measurement that uses propose-test-release to privatize a hashmap of counts.
• make_randomized_response
  Make a Measurement that implements randomized response on a categorical value.
• make_randomized_response_bool
  Make a Measurement that implements randomized response on a boolean value.
• post_process
  Wrap the AlpState in a Queryable object.
