Struct AccountInfo

pub struct AccountInfo {
    pub balance: U256,
    pub nonce: u64,
    pub code_hash: B256,
    pub code: Option<Bytecode>,
}

AccountInfo account information.

Fields

balance: U256

Account balance.

nonce: u64

Account nonce.

code_hash: B256

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: U256, nonce: u64, code_hash: B256, code: Bytecode) -> Self

Creates a new AccountInfo with the given fields.

pub fn copy_without_code(&self) -> Self

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) -> Self

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) -> B256

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: U256) -> Self

Initialize an AccountInfo with the given balance, setting all other fields to their default values.

pub fn from_bytecode(bytecode: Bytecode) -> Self

Initialize an AccountInfo with the given bytecode, setting its balance to zero, its nonce to 1, and calculating the code hash from the given bytecode.

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

Formats the value using the given formatter.

impl Default for AccountInfo

fn default() -> Self

Returns the “default value” for a type.

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

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<AccountInfo> for Account

fn from(info: AccountInfo) -> Self

Converts to this type from the input type.

impl Hash for AccountInfo

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

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: &Self) -> 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::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
