Enum ApprovalHandlerError 

pub enum ApprovalHandlerError {
    BadRequest(String),
    NotFound(String),
    Conflict(String),
    ReplayDetected(String),
    Rejected(String),
    Internal(String),
}

Errors returned by the approval handlers. Each variant maps onto a stable HTTP status so substrate adapters can relay the code without re-interpreting the semantics.

Variants

BadRequest(String)

Request body could not be parsed into the expected JSON shape.

NotFound(String)

Target approval id does not exist in the store.

Conflict(String)

Approval was already resolved (single-response rule).

ReplayDetected(String)

Replay detected: the signed token has already been consumed.

Rejected(String)

Approval token failed binding / signature / time checks.

Internal(String)

Backend store surfaced an internal error.

Trait Implementations

impl Clone for ApprovalHandlerError

fn clone(&self) -> ApprovalHandlerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ApprovalHandlerError

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

impl Error for ApprovalHandlerError

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
