Struct AccountInfo

pub struct AccountInfo {
    pub balance: Uint<256, 4>,
    pub nonce: u64,
    pub code_hash: FixedBytes<32>,
    pub code: Option<Bytecode>,
}

AccountInfo account information.

Fields

balance: Uint<256, 4>

Account balance.

nonce: u64

Account nonce.

code_hash: FixedBytes<32>

code hash,

code: Option<Bytecode>

code: if None, code_by_hash will be used to fetch it if code needs to be loaded from inside revm.

Implementations

impl AccountInfo

pub fn new( balance: Uint<256, 4>, nonce: u64, code_hash: FixedBytes<32>, code: Bytecode, ) -> AccountInfo

pub fn copy_without_code(&self) -> AccountInfo

Returns a copy of this account with the Bytecode removed. This is useful when creating journals or snapshots of the state, where it is desirable to store the code blobs elsewhere.

Note

This is distinct from AccountInfo::without_code in that it returns a new AccountInfo instance with the code removed. AccountInfo::without_code will modify and return the same instance.

pub fn without_code(self) -> AccountInfo

Strip the Bytecode from this account and drop it. This is useful when creating journals or snapshots of the state, where it is desirable to store the code blobs elsewhere.

Note

This is distinct from AccountInfo::copy_without_code in that it modifies the account in place. AccountInfo::copy_without_code will copy the non-code fields and return a new AccountInfo instance.

pub fn is_empty(&self) -> bool

Returns if an account is empty.

An account is empty if the following conditions are met.

• code hash is zero or set to the Keccak256 hash of the empty string ""
• balance is zero
• nonce is zero

pub fn exists(&self) -> bool

Returns true if the account is not empty.

pub fn has_no_code_and_nonce(&self) -> bool

Returns true if account has no nonce and code.

pub fn code_hash(&self) -> FixedBytes<32>

Return bytecode hash associated with this account. If account does not have code, it returns KECCAK_EMPTY hash.

pub fn is_empty_code_hash(&self) -> bool

Returns true if the code hash is the Keccak256 hash of the empty string "".

pub fn take_bytecode(&mut self) -> Option<Bytecode>

Take bytecode from account. Code will be set to None.

pub fn from_balance(balance: Uint<256, 4>) -> AccountInfo

pub fn from_bytecode(bytecode: Bytecode) -> AccountInfo

Trait Implementations

impl Clone for AccountInfo

fn clone(&self) -> AccountInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AccountInfo

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

Formats the value using the given formatter.

impl Default for AccountInfo

fn default() -> AccountInfo

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AccountInfo

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<AccountInfo> for Account

fn from(info: AccountInfo) -> Account

Converts to this type from the input type.

impl From<AccountInfo> for DbAccount

fn from(info: AccountInfo) -> DbAccount

Converts to this type from the input type.

impl From<AccountInfo> for PlainAccount

fn from(info: AccountInfo) -> PlainAccount

Converts to this type from the input type.

impl Hash for AccountInfo

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AccountInfo

fn eq(&self, other: &AccountInfo) -> 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 AccountInfo

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 AccountInfo

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
