Context block representation.

Fields and Validations

For more details, see the official documentation.

Field	Type	Required	Validation
elements	Vec<ContextElement>	Yes	Max 10 items
block_id	String	No	Maximum 255 characters

Example

The following is reproduction of the sample context.

use slack_messaging::mrkdwn;
use slack_messaging::blocks::Context;
use slack_messaging::blocks::elements::Image;

let context = Context::builder()
    .element(
        Image::builder()
            .image_url("https://image.freepik.com/free-photo/red-drawing-pin_1156-445.jpg")
            .alt_text("images")
            .build()?
    )
    .element(mrkdwn!("Location: **Dogpatch**")?)
    .build()?;

let expected = serde_json::json!({
    "type": "context",
    "elements": [
        {
            "type": "image",
            "image_url": "https://image.freepik.com/free-photo/red-drawing-pin_1156-445.jpg",
            "alt_text": "images"
        },
        {
            "type": "mrkdwn",
            "text": "Location: **Dogpatch**"
        }
    ]
});

let json = serde_json::to_value(context).unwrap();

assert_eq!(json, expected);

Implementations

impl Context

pub fn builder() -> ContextBuilder

constract ContextBuilder object.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Context

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Context> for Block

fn from(value: Context) -> Self

Converts to this type from the input type.

impl PartialEq for Context

fn eq(&self, other: &Context) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Context

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
