Implementations

impl Value

pub fn from_toml_value(value: TOMLValue) -> Result<Self>

pub fn from_string(text: String, format: Format) -> Result<Self>

Get the texts from a JSON string or TOML string.

Example JSON

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("\"Hi\""), Format::Json);
assert!(value.is_ok());
assert_eq!(value.unwrap(), Value::String(String::from("Hi")));

Example TOML

use std::collections::HashMap;

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("hi = \"Hi\""), Format::Toml);
assert!(value.is_ok());

let mut data: HashMap<String, Value> = HashMap::new();
data.insert(String::from("hi"), Value::String(String::from("Hi")));

assert_eq!(value.unwrap(), Value::Object(data));

pub fn is_string(&self) -> bool

Check if the current value is a string.

Example

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("\"Hi\""), Format::Json);
assert!(value.is_ok());
assert!(value.unwrap().is_string());

Example TOML

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("hi = \"Hi\""), Format::Toml);
assert!(value.is_ok());

let table = value.unwrap().get_object();
assert!(table.is_some());

let table = table.unwrap();
let text = table.get("hi");
assert!(text.is_some());
assert!(text.unwrap().is_string());

pub fn get_string(&self) -> Option<String>

Get the string value.

Example JSON

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("\"Hi\""), Format::Json);
assert!(value.is_ok());
assert_eq!(value.unwrap().get_string(), Some(String::from("Hi")));

Example TOML

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("hi = \"Hi\""), Format::Toml);
assert!(value.is_ok());

let table = value.unwrap().get_object();
assert!(table.is_some());

let table = table.unwrap();
let text = table.get("hi");
assert!(text.is_some());
assert_eq!(text.unwrap().get_string(), Some(String::from("Hi")));

pub fn is_array(&self) -> bool

Check if the current value is an array.

Example JSON

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("[\"1\", \"2\"]"), Format::Json);
assert!(value.is_ok());
assert!(value.unwrap().is_array());

Example TOML

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("numbers = [\"1\", \"2\"]"), Format::Toml);
assert!(value.is_ok());

let table = value.unwrap().get_object();
assert!(table.is_some());

let table = table.unwrap();
let values = table.get("numbers");
assert!(values.is_some());
assert!(values.unwrap().is_array());

pub fn get_array(&self) -> Option<Vec<Value>>

Get the array value.

Example JSON

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("[\"1\", \"2\"]"), Format::Json);
assert!(value.is_ok());
assert_eq!(value.unwrap().get_array(), Some(vec![Value::String(String::from("1")), Value::String(String::from("2"))]));

Example TOML

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("numbers = [\"1\", \"2\"]"), Format::Toml);
assert!(value.is_ok());

let table = value.unwrap().get_object();
assert!(table.is_some());

let table = table.unwrap();
let values = table.get("numbers");
assert!(values.is_some());
assert_eq!(values.unwrap().get_array(), Some(vec![Value::String(String::from("1")), Value::String(String::from("2"))]));

pub fn is_object(&self) -> bool

Check if the current value is an object.

Example JSON

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("{\"home\":{\"title\":\"Home page\"}}"), Format::Json);
assert!(value.is_ok());
assert!(value.unwrap().is_object());

Example TOML

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("[home]\r\ntitle = \"Home page\""), Format::Toml);
assert!(value.is_ok());
assert!(value.unwrap().is_object());

pub fn get_object(&self) -> Option<HashMap<String, Value>>

Get the object value.

Example JSON

use std::collections::HashMap;

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("{ \"title\": \"Home page\" }"), Format::Json);
assert!(value.is_ok());

let mut data: HashMap<String, Value> = HashMap::new();
data.insert(String::from("title"), Value::String(String::from("Home page")));

assert_eq!(value.unwrap().get_object(), Some(data));

Example TOML

use std::collections::HashMap;

use languages_rs::{Format, Value};

let value = Value::from_string(String::from("title = \"Home page\""), Format::Toml);
assert!(value.is_ok());

let mut data: HashMap<String, Value> = HashMap::new();
data.insert(String::from("title"), Value::String(String::from("Home page")));

assert_eq!(value.unwrap().get_object(), Some(data));
