Enum ContractError

pub enum ContractError<T> {
    CustomError(T),
    Revert(Revert),
    Panic(Panic),
}

A generic contract error.

Contains a Revert or Panic error, or a custom error.

If you want an empty CustomError variant, use GenericContractError.

Variants

CustomError(T)

A contract’s custom error.

Revert(Revert)

A generic revert. See Revert for more information.

Panic(Panic)

A panic. See Panic for more information.
