Trait Implementations

impl Clone for MessageHeader

fn clone(&self) -> MessageHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MessageHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageHeader

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

Deserialize this value from the given Serde deserializer.

impl PartialEq<MessageHeader> for MessageHeader

fn eq(&self, other: &MessageHeader) -> 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 Serialize for MessageHeader

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

Serialize this value into the given Serde serializer.

impl<'a> TryFrom<MessageHeaderRef<'a>> for MessageHeader

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.

impl StructuralPartialEq for MessageHeader

impl WriteAsOptionalUnion<MessageHeader> for MessageHeader

impl WriteAsUnion<MessageHeader> for MessageHeader
