Struct MessageMetadata

#[non_exhaustive]
pub struct MessageMetadata {
    pub message_id: Option<String>,
    pub receipts: Option<Vec<Receipt>>,
}

Contains metadata related to a message.

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.

message_id: Option<String>

The identifier of the message that contains the metadata information.

receipts: Option<Vec<Receipt>>

The list of receipt information for a message for different recipients.

Implementations

impl MessageMetadata

pub fn message_id(&self) -> Option<&str>

The identifier of the message that contains the metadata information.

pub fn receipts(&self) -> &[Receipt]

The list of receipt information for a message for different recipients.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .receipts.is_none().

impl MessageMetadata

pub fn builder() -> MessageMetadataBuilder

Creates a new builder-style object to manufacture MessageMetadata.

Trait Implementations

impl Clone for MessageMetadata

fn clone(&self) -> MessageMetadata

Returns a copy 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 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.
