:param int visibility_timeout:
Specifies the new visibility timeout value, in seconds,
relative to server time. The new value must be larger than or equal
to 0, and cannot be larger than 7 days. The visibility timeout of a
message cannot be set to a value later than the expiry time. A
message can be updated until it has been deleted or has expired.
:param obj content:
Message content. Allowed type is determined by the encode_function
set on the service. Default is str.
:param int timeout:
The server timeout, expressed in seconds.

A list of :class:`~azure.azure_async.queue.models.QueueMessage` objects. For convenience,
this object is also populated with the content, although it is not returned by the service.

Adds a new message to the back of the message queue.
The visibility timeout specifies the time that the message will be
invisible. After the timeout expires, the message will become visible.
If a visibility timeout is not specified, the default value of 0 is used.
The message time-to-live specifies how long a message will remain in the
queue. The message will be deleted from the queue when the time-to-live
period expires.
If the key-encryption-key field is set on the local service object, this method will
encrypt the content before uploading.
:param str queue_name:
The name of the queue to put the message into.
:param obj content:
Message content. Allowed type is determined by the encode_function
set on the service. Default is str. The encoded message can be up to
64KB in size.
:param int visibility_timeout:
If not specified, the default value is 0. Specifies the
new visibility timeout value, in seconds, relative to server time.
The value must be larger than or equal to 0, and cannot be
larger than 7 days. The visibility timeout of a message cannot be
set to a value later than the expiry time. visibility_timeout
should be set to a value smaller than the time-to-live value.
:param int time_to_live:
Specifies the time-to-live interval for the message, in
seconds. The maximum time-to-live allowed is 7 days. If this
parameter is omitted, the default time-to-live is 7 days.
:param int timeout:
The server timeout, expressed in seconds.
