Struct Variables

pub struct Variables { /* private fields */ }

Variables to be used in the request and response bodies.

The variables are used to replace placeholders in the request and response bodies in case some values need to be shared between requests and responses.

Examples

Variables can be passed one by one with specified type:

let mut variables = Variables::new();
variables.insert_string("name".to_string(), "John".to_string());
variables.insert_int("age".to_string(), 30);

A Value can be passed directly:

let mut variables = Variables::new();
variables.insert_value("name".to_string(), Value::String("John".to_string()));
variables.insert_value("age".to_string(), Value::Number(serde_json::Number::from(30)));

Alternatively, they can be passed as a JSON object:

let json = r#"{"name": "John", "age": 30}"#;
let variables = Variables::from_json(&serde_json::from_str(json).unwrap()).unwrap();

Implementations

impl Variables

pub fn new() -> Self

Constructs a new Variables.

Examples

let variables = Variables::new();

pub fn from_json(json: &Value) -> Result<Self, String>

Constructs a new Variables from a JSON object.

Examples

let json = r#"{"name": "John", "age": 30}"#;
let variables = Variables::from_json(&serde_json::from_str(json).unwrap()).unwrap();

pub fn insert_value(&mut self, name: String, value: Value)

Inserts a Value into the Variables.

This can be useful when more complex types are needed. Since Variables is a wrapper around HashMap if you insert duplicate keys the value will be overwritten.

Examples

let mut variables = Variables::new();
variables.insert_value("name".to_string(), Value::String("John".to_string()));

pub fn insert_string(&mut self, name: String, value: String)

Inserts a String into the Variables.

Examples

let mut variables = Variables::new();
variables.insert_string("name".to_string(), "John".to_string());

pub fn insert_int(&mut self, name: String, value: i64)

Inserts an i64 into the Variables.

Examples

let mut variables = Variables::new();
variables.insert_int("age".to_string(), 30);

pub fn insert_float(&mut self, name: String, value: f64)

Inserts an f64 into the Variables.

Examples

let mut variables = Variables::new();
variables.insert_float("age".to_string(), 30.0);

pub fn insert_bool(&mut self, name: String, value: bool)

Inserts a bool into the Variables.

Examples

let mut variables = Variables::new();
variables.insert_bool("is_adult".to_string(), true);

pub fn insert_null(&mut self, name: String)

Inserts a null into the Variables.

Examples

let mut variables = Variables::new();
variables.insert_null("name".to_string());

Trait Implementations

impl Clone for Variables

fn clone(&self) -> Variables

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Variables

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

Formats the value using the given formatter.

impl Default for Variables

fn default() -> Variables

Returns the “default value” for a type.
