Struct slack_blocks::blocks::Context

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

Context Block

slack api docs 🔗

Displays message context, which can include both images and text.

Implementations

impl<'a> Context<'a>

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

Build a new Context block.

For example, see docs for ContextBuilder.

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

Validate that this Context block agrees with Slack’s model requirements

Errors

• If with_block_id was called with a block id longer than 255 chars
• If from_elements, from_context_elements, or with_element was called with more than 10 objects

Example

use slack_blocks::{blocks::Context, text::ToSlackPlaintext};

let long_string = std::iter::repeat(' ').take(256).collect::<String>();

let block = Context::builder().element("foo".plaintext())
                              .block_id(long_string)
                              .build();

assert_eq!(true, matches!(block.validate(), Err(_)));
