Struct RpcFailure 

#[non_exhaustive]
pub struct RpcFailure { /* private fields */ }

Machine-readable RPC failure with no arbitrary provider or debug message.

Implementations

impl RpcFailure

pub fn application( code: impl Into<String>, retryable: bool, ) -> Result<Self, ClientContractError>

Creates an application failure from the bounded lowercase dotted-code grammar, such as counter.limit_reached.

pub fn code(&self) -> &str

Returns the stable failure code.

pub const fn retryable(&self) -> bool

Whether a retry may be appropriate. This never authorizes replaying a state-changing operation.

Trait Implementations

impl Clone for RpcFailure

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RpcFailure

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

Formats the value using the given formatter.

impl Display for RpcFailure

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

Formats the value using the given formatter.

impl Eq for RpcFailure

impl Error for RpcFailure

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 PartialEq for RpcFailure

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
