Struct MethodResponse 

pub struct MethodResponse { /* private fields */ }

Represents a response to a method call.

NOTE: A subscription is also a method call but it’s possible determine whether a method response is “subscription” or “ordinary method call” by calling MethodResponse::is_subscription

Implementations

impl MethodResponse

pub fn is_success(&self) -> bool

Returns whether the call was successful.

pub fn is_error(&self) -> bool

Returns whether the call failed.

pub fn is_subscription(&self) -> bool

Returns whether the response is a subscription response.

pub fn is_method_call(&self) -> bool

Returns whether the response is a method response.

pub fn is_batch(&self) -> bool

Returns whether the response is a batch response.

pub fn into_json(self) -> String

Consume the method response and extract the serialized JSON response.

pub fn to_json(&self) -> String

Get the serialized JSON response.

pub fn as_error_code(&self) -> Option<i32>

Get the error code

Returns Some(error code) if the call failed.

pub fn subscription_response<T>( id: Id<'_>, result: ResponsePayload<'_, T>, max_response_size: usize, ) -> MethodResponse

where T: Serialize + Clone,

This is similar to MethodResponse::response but sets a flag to indicate that response is a subscription.

pub fn response<T>( id: Id<'_>, rp: ResponsePayload<'_, T>, max_response_size: usize, ) -> MethodResponse

where T: Serialize + Clone,

Create a new method response.

If the serialization of result exceeds max_response_size then the response is changed to an JSON-RPC error object.

pub fn subscription_error<'a>( id: Id<'_>, err: impl Into<ErrorObject<'a>>, ) -> MethodResponse

This is similar to MethodResponse::error but sets a flag to indicate that error is a subscription.

pub fn error<'a>(id: Id<'_>, err: impl Into<ErrorObject<'a>>) -> MethodResponse

Create a MethodResponse from a JSON-RPC error.

pub fn notification() -> MethodResponse

Create notification response which is a response that doesn’t expect a reply.

Trait Implementations

impl AsRef<str> for MethodResponse

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Debug for MethodResponse

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

Formats the value using the given formatter.

impl Display for MethodResponse

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

Formats the value using the given formatter.

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.
