Trait Implementations

impl Clone for PreDefinedBounceClass

fn clone(&self) -> PreDefinedBounceClass

Returns a copy of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PreDefinedBounceClass

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PreDefinedBounceClass

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

Formats the value using the given formatter.

impl From<PreDefinedBounceClass> for BounceClass

fn from(c: PreDefinedBounceClass) -> BounceClass

Converts to this type from the input type.

impl FromStr for PreDefinedBounceClass

type Err = ParseError

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this type.

impl Hash for PreDefinedBounceClass

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for PreDefinedBounceClass

fn cmp(&self, other: &PreDefinedBounceClass) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
