Enum Id

pub enum Id<'a> {
    Null,
    Str(Cow<'a, str>),
    Int(i64),
    Uint(u64),
    Float(f64),
}

A request identifier.

JSON-RPC 2.0 clients can use this to match responses sent back by a complying server with the request they sent. This is especially useful when sending multiple requests at the same time without waiting for a response in between.

Variants

Null

The ID was null.

Str(Cow<'a, str>)

The ID was a string.

Int(i64)

The ID was a signed integer.

Uint(u64)

The ID was an unsigned integer.

Float(f64)

The ID was a floating point number.

Note

THe JSON-RPC 2.0 specification specifies that a client should not use floating point values as request IDs, but they technically are legal. For this reason, we have to account for them.

Implementations

impl<'a> Id<'a>

pub fn reborrow<'b>(&'b self) -> Id<'b>

where 'b: 'a,

Reborrows this Id, creating a new instance without reallocating.

Trait Implementations

impl<'a> Clone for Id<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Id<'a>

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

Formats the value using the given formatter.

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

where 'de: 'a,

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> From<&'a str> for Id<'a>

fn from(id: &'a str) -> Self

Converts to this type from the input type.

impl<'a> From<Cow<'a, str>> for Id<'a>

fn from(id: Cow<'a, str>) -> Self

Converts to this type from the input type.

impl<'a> From<String> for Id<'a>

fn from(id: String) -> Self

Converts to this type from the input type.

impl<'a> From<f64> for Id<'a>

fn from(id: f64) -> Self

Converts to this type from the input type.

impl<'a> From<i64> for Id<'a>

fn from(id: i64) -> Self

Converts to this type from the input type.

impl<'a> From<u64> for Id<'a>

fn from(id: u64) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for Id<'a>

fn eq(&self, other: &Id<'a>) -> 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<'a> Serialize for Id<'a>

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

where S: Serializer,

Serialize this value into the given Serde serializer.
