Struct NumberRef 

pub struct NumberRef<'a> { /* private fields */ }

A reference to a JSON number.

Implementations

impl NumberRef<'_>

pub fn to_number(self) -> Number

Dereferences the number.

pub fn as_u64(self) -> Option<u64>

If the number is an integer, returns the associated u64. Returns None otherwise.

pub fn as_i64(self) -> Option<i64>

If the number is an integer, returns the associated i64. Returns None otherwise.

pub fn as_f64(self) -> Option<f64>

Represents the number as f64 if possible. Returns None otherwise.

pub fn is_u64(self) -> bool

Returns true if the number can be represented by u64.

pub fn is_i64(self) -> bool

Returns true if the number can be represented by i64.

pub fn is_f64(self) -> bool

Returns true if the number can be represented by f64.

Trait Implementations

impl<'a> Clone for NumberRef<'a>

fn clone(&self) -> NumberRef<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumberRef<'_>

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

Formats the value using the given formatter.

impl Display for NumberRef<'_>

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

Formats the value using the given formatter.

impl Hash for NumberRef<'_>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NumberRef<'_>

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NumberRef<'_>

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for NumberRef<'_>

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for NumberRef<'_>

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
