Implementations

impl JsonValue

pub fn is_string(&self) -> bool

Checks if the value is the JsonValue::String discriminant.

Examples

use json_node::JsonValue;
 
let string_value = JsonValue::String("Hello World!".to_owned());
let non_string_value = JsonValue::Null;
 
assert!(string_value.is_string());
assert!(!non_string_value.is_string());

pub fn is_integer(&self) -> bool

Checks if the value is the JsonValue::Integer discriminant.

Examples

use json_node::JsonValue;
 
let integer_value = JsonValue::Integer(42);
let non_integer_value = JsonValue::Null;
 
assert!(integer_value.is_integer());
assert!(!non_integer_value.is_integer());

pub fn is_float(&self) -> bool

Checks if the value is the JsonValue::Float discriminant.

Examples

use json_node::JsonValue;
 
let float_value = JsonValue::Float(3.14);
let non_float_value = JsonValue::Null;
 
assert!(float_value.is_float());
assert!(!non_float_value.is_float());

pub fn is_bool(&self) -> bool

Checks if the value is the JsonValue::Boolean discriminant.

Examples

use json_node::JsonValue;
 
let bool_value = JsonValue::Boolean(true);
let non_bool_value = JsonValue::Null;
 
assert!(bool_value.is_bool());
assert!(!non_bool_value.is_bool());

pub fn is_null(&self) -> bool

Checks if the value is the JsonValue::Null discriminant.

Examples

use json_node::JsonValue;
 
let null_value = JsonValue::Null;
let non_null_value = JsonValue::Integer(42);
 
assert!(null_value.is_null());
assert!(!non_null_value.is_null());

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

Extracts the inner str contained inside the node if it is the JsonValue::String discriminant.

Examples

use json_node::JsonValue;
 
let string_value = JsonValue::String("Hello World!".to_owned());
let non_string_value = JsonValue::Null;
 
assert_eq!(string_value.as_string(), Some("Hello World!"));
assert_eq!(non_string_value.as_string(), None);

pub fn as_integer(&self) -> Option<&i64>

Extracts the inner i64 contained inside the node if it is the JsonValue::Integer discriminant.

Examples

use json_node::JsonValue;
 
let integer_value = JsonValue::Integer(42);
let non_integer_value = JsonValue::Null;
 
assert_eq!(integer_value.as_integer(), Some(&42));
assert_eq!(non_integer_value.as_integer(), None);

pub fn as_float(&self) -> Option<&f64>

Extracts the inner f64 contained inside the node if it is the JsonValue::Float discriminant.

Examples

use json_node::JsonValue;
 
let float_value = JsonValue::Float(3.14);
let non_float_value = JsonValue::Null;
 
assert_eq!(float_value.as_float(), Some(&3.14));
assert_eq!(non_float_value.as_float(), None);

pub fn as_boolean(&self) -> Option<&bool>

Extracts the inner bool contained inside the node if it is the JsonValue::Boolean discriminant.

Examples

use json_node::JsonValue;
 
let bool_value = JsonValue::Boolean(true);
let non_bool_value = JsonValue::Null;
 
assert_eq!(bool_value.as_boolean(), Some(&true));
assert_eq!(non_bool_value.as_boolean(), None);

pub fn as_string_mut(&mut self) -> Option<&mut str>

Extracts the inner mut str contained inside the node if it is the JsonValue::String discriminant.

Examples

use json_node::JsonValue;
 
let mut string_value = JsonValue::String("Hello World!".to_owned());
let mut non_string_value = JsonValue::Null;
 
assert_eq!(string_value.as_string_mut(), Some("Hello World!".to_string().as_mut_str()));
assert_eq!(non_string_value.as_string_mut(), None);

pub fn as_integer_mut(&mut self) -> Option<&mut i64>

Extracts the inner mut i64 contained inside the node if it is the JsonValue::Integer discriminant.

Examples

use json_node::JsonValue;
 
let mut integer_value = JsonValue::Integer(42);
let mut non_integer_value = JsonValue::Null;
 
assert_eq!(integer_value.as_integer_mut(), Some(&mut 42));

Trait Implementations

impl Clone for JsonValue

fn clone(&self) -> JsonValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JsonValue

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

Formats the value using the given formatter.

impl Display for JsonValue

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

impl PartialEq<JsonValue> for JsonValue

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

This method tests for self and other values to be equal, and is used by ==.

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

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