Block Elements - interactive components

slack api docs 🔗

Block elements can be used inside of section, context, and actions layout blocks 🔗. Inputs can only be used inside of input blocks.

Our overview of app surfaces that support Block Kit 🔗 shows you where those blocks might be relevant.

Finally, our handling user interactivity guide 🔗 will help you prepare your app to allow for the use of the interactive components listed below.

Implementations

impl<'a> BlockElement<'a>

pub fn validate(&self) -> Result<(), ValidationErrors>

Available on crate feature validation only.

Validate that this block element agrees with Slack’s model requirements.

use slack_blocks::elems::{BlockElement, Button};

let text = std::iter::repeat('a').take(76).collect::<String>();
let btn = Button::builder().text(text).action_id("").build();

let elem = BlockElement::from(btn.clone());

assert_eq!(elem.validate(), btn.validate())
