Struct solana_libra_types::access_path::AccessPath

pub struct AccessPath {
    pub address: AccountAddress,
    pub path: Vec<u8>,
}

Fields

address: AccountAddress

path: Vec<u8>

Methods

impl AccessPath

pub fn new(address: AccountAddress, path: Vec<u8>) -> Self

pub fn new_for_account(address: AccountAddress) -> Self

Given an address, returns the corresponding access path that stores the Account resource.

pub fn new_for_event(address: AccountAddress, root: &[u8], key: &[u8]) -> Self

Create an AccessPath for a ContractEvent. That is an AccessPah that uniquely identifies a given event for a published resource.

pub fn new_for_sent_event(address: AccountAddress) -> Self

Create an AccessPath to the event for the sender account in a deposit operation. The sent counter in LibraAccount.T (LibraAccount.T.sent_events_count) is used to generate the AccessPath. That AccessPath can be used as a key into the event storage to retrieve all sent events for a given account.

pub fn new_for_received_event(address: AccountAddress) -> Self

Create an AccessPath to the event for the target account (the receiver) in a deposit operation. The received counter in LibraAccount.T (LibraAccount.T.received_events_count) is used to generate the AccessPath. That AccessPath can be used as a key into the event storage to retrieve all received events for a given account.

pub fn resource_access_vec(tag: &StructTag, accesses: &Accesses) -> Vec<u8>

pub fn resource_access_path(
    key: &ResourceKey,
    accesses: &Accesses
) -> AccessPath

Convert Accesses into a byte offset which would be used by the storage layer to resolve where fields are stored.

pub fn code_access_path(key: &ModuleId) -> AccessPath
