Struct MessageMetadata 

#[non_exhaustive]
pub struct MessageMetadata {
    pub user_id: Option<String>,
}

Optional metadata sent with a Messages request.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

user_id: Option<String>

Stable user identifier; passed through to abuse-detection systems.

Implementations

impl MessageMetadata

pub fn with_user(user_id: impl Into<String>) -> Self

Convenience constructor that sets user_id.

Trait Implementations

impl Clone for MessageMetadata

fn clone(&self) -> MessageMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageMetadata

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

Formats the value using the given formatter.

impl Default for MessageMetadata

fn default() -> MessageMetadata

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MessageMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MessageMetadata

fn eq(&self, other: &MessageMetadata) -> 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 MessageMetadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for MessageMetadata
