Enum evmc_sys::evmc_storage_status

#[repr(u32)]pub enum evmc_storage_status {
    EVMC_STORAGE_UNCHANGED,
    EVMC_STORAGE_MODIFIED,
    EVMC_STORAGE_MODIFIED_AGAIN,
    EVMC_STORAGE_ADDED,
    EVMC_STORAGE_DELETED,
}

The effect of an attempt to modify a contract storage item.

For the purpose of explaining the meaning of each element, the following notation is used:

• 0 is zero value,
• X != 0 (X is any value other than 0),
• Y != X, Y != 0 (Y is any value other than X and 0),
• Z != Y (Z is any value other than Y),
• the "->" means the change from one value to another.

Variants

EVMC_STORAGE_UNCHANGED

The value of a storage item has been left unchanged: 0 -> 0 and X -> X.

EVMC_STORAGE_MODIFIED

The value of a storage item has been modified: X -> Y.

EVMC_STORAGE_MODIFIED_AGAIN

A storage item has been modified after being modified before: X -> Y -> Z.

EVMC_STORAGE_ADDED

A new storage item has been added: 0 -> X.

EVMC_STORAGE_DELETED

A storage item has been deleted: X -> 0.
