Trait Implementations

impl Clone for PCTSignatures_SimilarityFunction

fn clone(&self) -> PCTSignatures_SimilarityFunction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PCTSignatures_SimilarityFunction

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

Formats the value using the given formatter.

impl From<PCTSignatures_SimilarityFunction> for i32

fn from(v: PCTSignatures_SimilarityFunction) -> Self

Converts to this type from the input type.

impl PartialEq for PCTSignatures_SimilarityFunction

fn eq(&self, other: &PCTSignatures_SimilarityFunction) -> 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 TryFrom<i32> for PCTSignatures_SimilarityFunction

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.
