Struct Error 

pub struct Error { /* private fields */ }

An object suitable to be returned in a JSON-RPC response as the “error” field.

See the JSON-RPC Specification for further details.

Implementations

impl Error

pub fn new<C: ErrorCodeT, T: Serialize>( error_code: C, additional_info: T, ) -> Self

Returns a new Error, converting error_code to the “code” and “message” fields, and JSON-encoding additional_info as the “data” field.

Other than when providing a ReservedErrorCode, the converted “code” must not fall in the reserved range as defined in the JSON-RPC specification, i.e. it must not be between -32768 and -32100 inclusive.

Note that in an upcoming release, the restriction will be tightened to disallow error codes in the implementation-defined server-errors range. I.e. codes in the range -32768 to -32000 inclusive will be disallowed.

If the converted code is within the reserved range when it should not be, or if JSON-encoding additional_data fails, the returned Self is built from ReservedErrorCode::InternalError with the “data” field being a String providing more info on the underlying error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Error

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Error

fn eq(&self, other: &Error) -> 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 Serialize for Error

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
