Struct slack_blocks::elems::overflow::Overflow

pub struct Overflow<'a> { /* fields omitted */ }

Overflow Menu

This is like a cross between a button and a select menu - when a user clicks on this overflow button, they will be presented with a list of options to choose from.

Unlike the select menu, there is no typeahead field, and the button always appears with an ellipsis (“…”), rather than customisable text.

Implementations

impl<'a> Overflow<'a>

pub fn builder() -> OverflowBuilderInit<'a>

Construct a new Overflow Menu.

Example

See example of build::OverflowBuilder

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

This is supported on crate feature validation only.

Validate that this select element agrees with Slack’s model requirements

Errors

• length of action_id greater than 255
• length of options less than 2 or greater than 5
• one or more of options is invalid (TODO)
• confirm is set and an invalid Confirm

Example

use slack_blocks::{compose::Opt, elems::Overflow};

fn repeat<T: Copy>(el: T, n: usize) -> impl Iterator<Item = T> {
  std::iter::repeat(el).take(n)
}

let long_string: String = repeat('a', 256).collect();

let opt = Opt::builder().text_plain("foo")
                        .value("bar")
                        .no_url()
                        .build();

let opts: Vec<Opt<_, _>> = repeat(&opt, 6).map(|o| o.clone()).collect();

let input = Overflow::builder().action_id(long_string) // invalid
                               .options(opts) // also invalid
                               .build();

assert!(matches!(input.validate(), Err(_)))
