Enum frame_support::dispatch::DispatchError

pub enum DispatchError {
    Other(&'static str),
    CannotLookup,
    BadOrigin,
    Module {
        index: u8,
        error: u8,
        message: Option<&'static str>,
    },
}

Reason why a dispatch call failed.

Variants

Other(&'static str)

Some error occurred.

CannotLookup

Failed to lookup some data.

BadOrigin

A bad origin.

Module

A custom error in a module.

Fields of Module

index: u8

Module index, matching the metadata module index.

error: u8

Module specific error value.

message: Option<&'static str>

Optional error message.
