Struct slack_messaging::blocks::elements::Image

pub struct Image { /* private fields */ }

Image element representation.

Example

use slack_messaging::blocks::elements::Image;
use serde_json::json;

let image = Image::new()
    .set_image_url("http://placekitten.com/700/500")
    .set_alt_text("Multiple cute kittens");

let expected = json!({
    "type": "image",
    "image_url": "http://placekitten.com/700/500",
    "alt_text": "Multiple cute kittens"
});

let image_json = serde_json::to_value(image).unwrap();

assert_eq!(image_json, expected);
