Enum Scale 

pub enum Scale {
    Linear,
    Log,
    ReverseLog,
}

Scale for continuous search ranges.

Governs how samplers interpolate between low and high: which values a grid places its points at and where random draws concentrate.

Variants

Linear

Uniform spacing across the range.

Log

Logarithmic spacing: samples concentrate near the low end. The right choice for learning rates and regularization strengths, where orders of magnitude matter more than absolute differences.

ReverseLog

Mirror image of Scale::Log: samples concentrate near the high end. Useful for parameters like momentum or keep probability, where the interesting region is close to the upper bound.

Trait Implementations

impl Clone for Scale

fn clone(&self) -> Scale

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Scale

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Scale

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Scale

fn eq(&self, other: &Scale) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Scale

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Scale

impl Eq for Scale
