Struct DiffMode 

pub struct DiffMode {
    pub post: BTreeMap<Address, AccountState>,
    pub pre: BTreeMap<Address, AccountState>,
}

Represents the account states before and after the transaction is executed.

This corresponds to the DiffMode of the PreStateConfig.

This will only contain changed AccountStates, created accounts will not be included in the pre state and selfdestructed accounts will not be included in the post state.

Fields

post: BTreeMap<Address, AccountState>

The account states after the transaction is executed.

pre: BTreeMap<Address, AccountState>

The account states before the transaction is executed.

Implementations

impl DiffMode

pub fn retain_changed(&mut self) -> &mut DiffMode

The sets of the DiffMode should only contain changed AccountStates.

This will remove all unchanged AccountStates from the sets.

In other words it removes entries that are equal (unchanged) in both the pre and post sets.

pub fn remove_zero_storage_values(&mut self)

Removes all zero values from the storage of the AccountStates.

Trait Implementations

impl Clone for DiffMode

fn clone(&self) -> DiffMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DiffMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for DiffMode

fn default() -> DiffMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DiffMode

fn deserialize<__D>( __deserializer: __D, ) -> Result<DiffMode, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DiffMode

fn eq(&self, other: &DiffMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DiffMode

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for DiffMode
