Struct Message

#[non_exhaustive]
pub struct Message { pub message_id: Option<String>, pub receipt_handle: Option<String>, pub md5_of_body: Option<String>, pub body: Option<String>, pub attributes: Option<HashMap<MessageSystemAttributeName, String>>, pub md5_of_message_attributes: Option<String>, pub message_attributes: Option<HashMap<String, MessageAttributeValue>>, }
Expand description

An Amazon SQS message.

Fields (Non-exhaustive)§

This struct is marked as 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>

A unique identifier for the message. A MessageIdis considered unique across all Amazon Web Services accounts for an extended period of time.

§receipt_handle: Option<String>

An identifier associated with the act of receiving the message. A new receipt handle is returned every time you receive a message. When deleting a message, you provide the last received receipt handle to delete the message.

§md5_of_body: Option<String>

An MD5 digest of the non-URL-encoded message body string.

§body: Option<String>

The message's contents (not URL-encoded).

§attributes: Option<HashMap<MessageSystemAttributeName, String>>

A map of the attributes requested in ReceiveMessage to their respective values. Supported attributes:

  • ApproximateReceiveCount

  • ApproximateFirstReceiveTimestamp

  • MessageDeduplicationId

  • MessageGroupId

  • SenderId

  • SentTimestamp

  • SequenceNumber

ApproximateFirstReceiveTimestamp and SentTimestamp are each returned as an integer representing the epoch time in milliseconds.

§md5_of_message_attributes: Option<String>

An MD5 digest of the non-URL-encoded message attribute string. You can use this attribute to verify that Amazon SQS received the message correctly. Amazon SQS URL-decodes the message before creating the MD5 digest. For information about MD5, see RFC1321.

§message_attributes: Option<HashMap<String, MessageAttributeValue>>

Each message attribute consists of a Name, Type, and Value. For more information, see Amazon SQS message attributes in the Amazon SQS Developer Guide.
