Enum Content 

pub enum Content {
    Text(String),
    Object(Map<String, Value>),
    Array(Vec<Value>),
}

A string, JSON object or JSON array.

The API accepts exactly these three shapes for request state, question instructions, Choice option descriptions and Score levels. A string suits simple text; an object with named fields suits content that has several parts.

Object fields are kept in serde_json::Map order: sorted by key, unless your application enables serde_json’s preserve_order feature.

use serde_json::json;
use typesafe_client::Content;

let text = Content::from("My card was charged twice.");
let record = Content::from(json!({ "message": "My card was charged twice.", "order_id": "A-104" }));

assert_eq!(text.as_text(), Some("My card was charged twice."));
assert!(matches!(record, Content::Object(_)));

Variants

Text(String)

Plain text.

Object(Map<String, Value>)

A JSON object with named fields.

Array(Vec<Value>)

A JSON array, such as a sequence of messages.

Implementations

impl Content

pub fn json<T: Serialize + ?Sized>(value: &T) -> Result<Self, Error>

Serializes value into content, for example an application struct used as state.

Numbers, booleans and null become their JSON text, because the API only accepts strings, objects and arrays. The error converts into Error with ?.

pub fn as_text(&self) -> Option<&str>

The text, if this is Content::Text.
