Enum pact_consumer::patterns::JsonPattern

pub enum JsonPattern {
    Json(Value),
    Array(Vec<JsonPattern>),
    Object(HashMap<String, JsonPattern>),
    Pattern(Box<dyn Pattern<Matches = Value>>),
}

A pattern which can be used to either:

1. generate a sample JSON value using to_json, or
2. test whether a JSON value matches the pattern.

Many common Rust types may be converted into JSON patterns using into(), or the provided helper functions:

use pact_consumer::prelude::*;

let s: JsonPattern = "example".into();
let b: JsonPattern = true.into();
let v: JsonPattern = vec!["a", "b"].into();
let n = JsonPattern::null();

For more complicated values, see the json_pattern! macro.

Variants

Json(Value)

A regular JSON value, implemented by serde_json::Value. Contains no special matching rules.

Array(Vec<JsonPattern>)

An array of JSON patterns. May contain nested matching rules.

Object(HashMap<String, JsonPattern>)

An object containing JSON patterns. May contain nested matching rules.

Pattern(Box<dyn Pattern<Matches = Value>>)

A term which contains an arbitrary matchable. This is where rules like Like hook into our syntax.

Implementations

impl JsonPattern

pub fn null() -> JsonPattern

Construct a JSON null value.

pub fn pattern<P>(pattern: P) -> JsonPattern

where P: Pattern<Matches = Value> + 'static,
