Public Channel Select

slack api docs 🔗

This select menu will populate its options with a list of public channels visible to the current user in the active workspace.

Implementations

impl<'a> PublicChannel<'a>

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

Build a new public channel select element

Examples

use std::convert::TryFrom;

use slack_blocks::{blocks::{Actions, Block},
                   compose::Opt,
                   elems::{select, BlockElement},
                   text};

let select: BlockElement =
  select::PublicChannel::builder().placeholder("Choose your favorite channel!")
                                 .action_id("fave_channel")
                                 .build()
                                 .into();

let block: Block = Actions::try_from(select).unwrap().into();

pub fn from_placeholder_and_action_id(
    placeholder: impl Into<Plain>,
    action_id: impl Into<Cow<'a, str>>
) -> Self

👎 Deprecated since 0.16.10:

use elems::select::PublicChannel::builder instead.

Construct a Select element, with a data source of the Public Channels in the user’s Workspace.

Arguments

• placeholder - A plain_text only text object 🔗 that defines the placeholder text shown on the menu. Maximum length for the text in this field is 150 characters.

• action_id - An identifier for the action triggered when a menu option is selected. You can use this when you receive an interaction payload to identify the source of the action 🔗. Should be unique among all other action_ids used elsewhere by your app. Maximum length for this field is 255 characters.

Example

use slack_blocks::elems::select;
use slack_blocks::blocks;
use slack_blocks::text;

let select = select::PublicChannel::from_placeholder_and_action_id(
    "Pick a Channel...",
    "ABC123"
);

let blocks: Vec<blocks::Block> = vec![
    blocks::Section::from_text(text::Plain::from(
        "Pick a channel to send your poll to...")
    ).into(),
    blocks::Actions::from_action_elements(vec![select.into()]).into(),
];

pub fn with_confirm(self, confirm: Confirm) -> Self

👎 Deprecated since 0.16.10:

use elems::select::PublicChannel::builder instead.

Optional method that allows you to add a confirmation dialog that appears after a menu item is selected.

Arguments

• confirm - A confirm object 🔗 that defines an optional confirmation dialog that appears after a menu item is selected.

Example

use slack_blocks::elems::select;
use slack_blocks::text;
use slack_blocks::blocks;
use slack_blocks::compose;

let confirm = compose::Confirm::from_parts(
    "Confirm Poll Channel",
    text::Plain::from(
        "Are you sure this is the channel you want to send this to?"
    ),
    "Yep, I'm sure",
    "No way!"
);

let select = select::PublicChannel::from_placeholder_and_action_id(
        "Pick a Channel...",
        "ABC123"
    )
    .with_confirm(confirm);

let blocks: Vec<blocks::Block> = vec![
    blocks::Section::from_text(text::Plain::from(
        "Pick a channel to send your poll to..."
    )).into(),
    blocks::Actions::from_action_elements(vec![select.into()]).into(),
];

pub fn with_initial_channel(self, channel_id: impl Into<Cow<'a, str>>) -> Self

👎 Deprecated since 0.16.10:

use elems::select::PublicChannel::builder instead.

Optional method that allows you to set a pre-selected channel in the select menu with the channel’s ID.

Arguments

• channel - The ID of any valid public channel to be pre-selected when the menu loads.

Example

use slack_blocks::elems::select;
use slack_blocks::text;
use slack_blocks::blocks;
use slack_blocks::compose;

let confirm = compose::Confirm::from_parts(
    "Confirm Poll Channel",
    text::Plain::from(
        "Are you sure this is the channel you want to send this to?"
    ),
    "Yep, I'm sure",
    "No way!"
);
let channel_general = ("#general", "C12345");
let select = select::PublicChannel::from_placeholder_and_action_id(
        "Pick a Channel...",
        "ABC123"
    )
    .with_confirm(confirm)
    .with_initial_channel(channel_general.1);

let blocks: Vec<blocks::Block> = vec![
    blocks::Section::from_text(text::Plain::from(
        "Pick a channel to send your poll to..."
    )).into(),
    blocks::Actions::from_action_elements(vec![select.into()]).into(),
];

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

Validate that this Public Channel Select element agrees with Slack’s model requirements

Errors

• If from_placeholder_and_action_id was called with placeholder longer than 150 chars
• If from_placeholder_and_action_id was called with action_id longer than 255 chars

Example

use slack_blocks::elems::select;

let select = select::PublicChannel::from_placeholder_and_action_id(
        r#"Hey I really would appreciate it if you chose
        a channel relatively soon, so that we can figure out
        where we need to send this poll, ok? it's kind of
        important that you specify where this poll should be
        sent, in case we haven't made that super clear.
        If you understand, could you pick a channel, already??"#,
        "ABC123"
    );

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