Enum Id 

pub enum Id {
    Number(u64),
    String(String),
    None,
}

A JSON-RPC 2.0 ID object. This may be a number, a string, or null.

Ordering

This type implements PartialOrd, Ord, PartialEq, and Eq so that it can be used as a key in a BTreeMap or an item in a BTreeSet. The ordering is as follows:

1. Numbers are less than strings.
2. Strings are less than null.
3. Null is equal to null.

Hash

This type implements Hash so that it can be used as a key in a HashMap or an item in a HashSet.

Variants

Number(u64)

A number.

String(String)

A string.

None

Null.

Implementations

impl Id

pub const fn is_number(&self) -> bool

Returns true if the ID is a number.

pub const fn is_string(&self) -> bool

Returns true if the ID is a string.

pub const fn is_none(&self) -> bool

Returns true if the ID is None.

pub const fn as_number(&self) -> Option<u64>

Returns the ID as a number, if it is one.

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

Returns the ID as a string, if it is one.

Trait Implementations

impl Clone for Id

fn clone(&self) -> Id

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Id

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Id

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Id

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

Formats the value using the given formatter.

impl From<String> for Id

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<u64> for Id

fn from(value: u64) -> Self

Converts to this type from the input type.

impl Hash for Id

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 Id

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 Id

fn eq(&self, other: &Id) -> 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 Id

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 Id

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

Serialize this value into the given Serde serializer.

impl Eq for Id

impl StructuralPartialEq for Id

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
