Struct UserError 

pub struct UserError {
    pub code: i32,
    pub message: String,
    pub data: Option<Box<RawValue>>,
}

This error should be returned when the user is at fault making a call, for instance because the method name was wrong, parameters invalid or some invariant not upheld. Implementations of RpcClientT should turn any such errors into this, so that they can be handled appropriately. By contrast, Error::Client is emitted when the underlying RPC Client implementation has some problem that isn’t user specific (eg network issues or similar).

Implementations

impl UserError

pub fn method_not_found() -> UserError

Returns a standard JSON-RPC “method not found” error.

Trait Implementations

impl Clone for UserError

fn clone(&self) -> UserError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UserError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UserError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for UserError

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

Formats the value using the given formatter.

impl Error for UserError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<UserError> for Error

fn from(source: UserError) -> Self

Converts to this type from the input type.
