Struct azure_functions::bindings::QueueMessage

pub struct QueueMessage(_);

Represents an Azure Storage Queue message output binding.

Examples

Creating a queue message from a string:

use azure_functions::bindings::QueueMessage;

let message: QueueMessage = "hello world!".into();
assert_eq!(message.as_str().unwrap(), "hello world!");

Creating a queue message from a JSON value (see the json! macro from the serde_json crate):

use azure_functions::bindings::QueueMessage;

let message: QueueMessage = json!({ "hello": "world!" }).into();

assert_eq!(message.as_str().unwrap(), r#"{"hello":"world!"}"#);

Creating a queue message from a sequence of bytes:

use azure_functions::bindings::QueueMessage;

let message: QueueMessage = [1, 2, 3][..].into();

assert_eq!(
    message.as_bytes(),
    [1, 2, 3]
);
