Enum BridgeError 

pub enum BridgeError {
    NotFound,
    InvalidArgument,
    ReadOnly,
    Internal,
    AbiMismatch,
}

Failure of an SDK call into CCF.

Conversion to EndpointError, as by ? in a handler, always gives HTTP 500.

Variants

NotFound

A value was not found. Lookups report this as None or false instead.

InvalidArgument

CCF rejected an argument, such as an empty map name, an unknown status or an invalid header.

ReadOnly

A write was attempted in a read-only transaction.

Internal

CCF failed the operation, or returned invalid UTF-8 where a string was expected.

AbiMismatch

The SDK and CCF were built with different ABI versions.

Trait Implementations

impl Clone for BridgeError

fn clone(&self) -> BridgeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BridgeError

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

Formats the value using the given formatter.

impl From<BridgeError> for EndpointError

Convert to an HTTP 500 InternalError, so that ? can be used in handlers.

use ccf_app::{BridgeError, EndpointError};

let error = EndpointError::from(BridgeError::InvalidArgument);
assert_eq!(error.status, 500);
assert_eq!(error.message, "CCF bridge error: InvalidArgument");

fn from(error: BridgeError) -> Self

Converts to this type from the input type.

impl PartialEq for BridgeError

fn eq(&self, other: &BridgeError) -> 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.
