}Expand description
A trait for types representing distribution parameters, for a given unsigned integer type.
Required Methods§
Sourcefn get_standard_dev(&self) -> f64
fn get_standard_dev(&self) -> f64
Returns the standard deviation of the distribution, i.e. $\sigma = 2^p$.
Sourcefn get_variance(&self) -> f64
fn get_variance(&self) -> f64
Returns the variance of the distribution, i.e. $\sigma^2 = 2^{2p}$.
Sourcefn get_log_standard_dev(&self) -> f64
fn get_log_standard_dev(&self) -> f64
Returns base 2 logarithm of the standard deviation of the distribution, i.e. $\log_2(\sigma)=p$
Sourcefn get_modular_standard_dev(&self, log2_modulus: u32) -> f64
fn get_modular_standard_dev(&self, log2_modulus: u32) -> f64
For a Uint type representing $\mathbb{Z}/2^q\mathbb{Z}$, we return $2^{q-p}$.
Sourcefn get_modular_variance(&self, log2_modulus: u32) -> f64
fn get_modular_variance(&self, log2_modulus: u32) -> f64
For a Uint type representing $\mathbb{Z}/2^q\mathbb{Z}$, we return $2^{2(q-p)}$.
Sourcefn get_modular_log_standard_dev(&self, log2_modulus: u32) -> f64
fn get_modular_log_standard_dev(&self, log2_modulus: u32) -> f64
For a Uint type representing $\mathbb{Z}/2^q\mathbb{Z}$, we return $q-p$.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
