    pub transactions: Vec<UserTransactionData>,
}

Fields

Implementations

impl UserChainData

pub fn default() -> Self

Creates a default ChainData with nonce 0 and an empty transactions vector.

pub fn new(transaction: UserTransactionData) -> Self

pub fn add(&mut self, nonce: u64, transaction: UserTransactionData)

Adds a new transaction to the chain and updates the nonce.

pub fn remove( &mut self, index: usize, ) -> Result<&UserTransactionData, UserStateError>

Removes a transaction from the specified chain and updates the ChainData. Returns an error if the chain_id is not found. Returns an error if the transaction index is not found.

pub fn get_transaction( &self, index: usize, ) -> Result<&UserTransactionData, UserStateError>

Returns a reference to the transaction at the specified index.

pub fn get_transactions(&self) -> &Vec<UserTransactionData>

pub fn add_transaction( &mut self, nonce: u64, transaction: UserTransactionData, ) -> Result<&UserTransactionData, UserStateError>

Adds a transaction to the specified chain and updates the ChainData. Returns an error if the chain_id is not found.

pub fn clear_transactions(&mut self)

Clears the transactions vector for the specified chain. Returns an error if the chain_id is not found.

Trait Implementations

impl CandidType for UserChainData

fn _ty() -> Type

fn id() -> TypeId

fn idl_serialize<__S>(&self, __serializer: __S) -> Result<(), __S::Error>

where __S: Serializer,

fn ty() -> Type

impl Clone for UserChainData

fn clone(&self) -> UserChainData

Returns a duplicate of the value.

Performs copy-assignment from source.

impl Debug for UserChainData

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UserChainData

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for UserChainData

fn eq(&self, other: &UserChainData) -> 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.
