#[non_exhaustive]#[repr(u32)]pub enum LangError {
CouldNotReadInput = 1,
}
Expand description
An error emitted by the smart contracting language.
This is different than errors from:
- Errors from the contract, which are programmer defined
- Errors from the underlying execution environment (e.g
pallet-revive
)
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
CouldNotReadInput = 1
Failed to read execution input for the dispatchable.
