Enum adventjson::JsonObject

pub enum JsonObject {
    Array(Vec<Self>),
    Obj(Vec<(String, Self)>),
    Number(f64),
    JsonStr(String),
    Bool(bool),
    Null,
}

A json object

A full json object

Notes

In accordance to the specification a Number may not be NaN or one of the Infinity-ies, so it is Eq and Ord

Variants

Array(Vec<Self>)

An array of objects (e.g.: [1,2,3])

Obj(Vec<(String, Self)>)

Key-value pairs (e.g.: {"first": 10, "other": 15})

Number(f64)

A number (e.g.: -0.08333)

JsonStr(String)

A string (e.g.: "Test: \"")

Bool(bool)

A boolean (e.g. true)

Null

The null-value

Implementations

impl JsonObject

pub fn partial_read(
    s: &[char],
    newindex: usize
) -> Result<(Self, usize), JsonError>

Reads a json object partially

Reads a JsonObject partially and returns both, it and where the next character should be read.

Errors

Returns an JsonError if the input was invalid.

pub fn read(s: &str) -> Result<Self, JsonError>

Reads a json object

Reads a JsonObject or returns an error.

Errors

Returns an JsonError if the input was invalid.

#[must_use]

pub fn unique(&self) -> bool

Checks if all keys are unique

RFC 8259 requires all keys in objects (“{"one": 1, "twenty": 20}”) to be unique. This function checks recursively if that condition is met.

Trait Implementations

impl Clone for JsonObject

fn clone(&self) -> JsonObject

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JsonObject

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

Formats the value using the given formatter.

impl Default for JsonObject

fn default() -> Self

The default value is JsonObject::Null

impl Display for JsonObject

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

Formats the value using the given formatter.

impl Ord for JsonObject

Save because no not-number values are allowed in json

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

#[must_use]

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<JsonObject> for JsonObject

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

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

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

This method tests for !=.

impl PartialOrd<JsonObject> for JsonObject

fn partial_cmp(&self, other: &JsonObject) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Eq for JsonObject
