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 copy 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
