Struct MessageMeta 

pub struct MessageMeta {
    pub used_size: usize,
    pub values: BTreeMap<String, MetaValue>,
}

Dynamic metadata envelope for schema-less receive operations.

Fields

used_size: usize

Number of payload bytes that are valid for this message.

values: BTreeMap<String, MetaValue>

Additional metadata fields.

Trait Implementations

impl ChannelMetadata for MessageMeta

fn used_size(&self) -> usize

Returns the number of payload bytes that are valid for this message.

impl Clone for MessageMeta

fn clone(&self) -> MessageMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageMeta

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageMeta

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MessageMeta

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

impl Serialize for MessageMeta

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
