Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for AlternateProtocolUsage

fn clone(&self) -> AlternateProtocolUsage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AlternateProtocolUsage

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

fn deserialize<__D>( __deserializer: __D, ) -> Result<AlternateProtocolUsage, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for AlternateProtocolUsage

type Err = String

The associated error which can be returned from parsing.

fn from_str( s: &str, ) -> Result<AlternateProtocolUsage, <AlternateProtocolUsage as FromStr>::Err>

fn eq(&self, other: &AlternateProtocolUsage) -> 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.
