Expand description

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.

Show fields

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.

ConsumerRemaining

At least one consumer is remaining so the account cannot be destroyed.

NoProviders

There are no providers so the account cannot be created.

Token(TokenError)

An error to do with tokens.

Arithmetic(ArithmeticError)

An arithmetic error.

Implementations
