Struct TransitionAccount 

Source 
pub struct TransitionAccount<S = StorageWithOriginalValues> {
    pub info: Option<AccountInfo>,
    pub status: AccountStatus,
    pub previous_info: Option<AccountInfo>,
    pub previous_status: AccountStatus,
    pub storage: S,
    pub storage_was_destroyed: bool,
}
Expand description

Account Created when EVM state is merged to cache state. And it is sent to Block state.

It is used when block state gets merged to bundle state to create needed Reverts.

Fields§

§info: Option<AccountInfo>

Account information, if account exists.

§status: AccountStatus

Current account status.

§previous_info: Option<AccountInfo>

Previous account info is needed for account that got initially loaded. Initially loaded account are not present inside bundle and are needed to generate Reverts.

§previous_status: AccountStatus

Mostly needed when previous status Loaded/LoadedEmpty.

§storage: S

Storage contains both old and new account

§storage_was_destroyed: bool

If there is transition that clears the storage we should mark it here and delete all storages in BundleState. This flag is needed if we have transition between Destroyed states from DestroyedChanged-> DestroyedAgain-> DestroyedChanged in the end transition that we would have would be DestroyedChanged->DestroyedChanged and with only that info we couldn’t decide what to do.
