Trait Implementations§

fn clone(&self) -> Footer

Returns a copy of the value. Read more

1.0.0 · source§

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

Performs copy-assignment from source. Read more

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

Formats the value using the given formatter. Read more

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where
__D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer. Read more

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

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

1.0.0 · source§

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.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where
S: Serializer,

Serialize this value into the given Serde serializer. Read more

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: FooterRef<'a>) -> Result<Self>

Performs the conversion.
