Implementations

Trait Implementations

impl StructuralEq for PNMSubtype

impl Eq for PNMSubtype

impl PartialEq for PNMSubtype

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Clone for PNMSubtype

fn clone(&self) -> PNMSubtype

Returns a copy of the value.

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

Performs copy-assignment from source.

impl StructuralPartialEq for PNMSubtype

impl Copy for PNMSubtype

impl Debug for PNMSubtype

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

Formats the value using the given formatter.
