pub struct NetworkAccount { /* private fields */ }Expand description
A wrapper around an Account that is guaranteed to be a network account.
§Specification
An Account is a network account if and only if all of the following hold:
- It MUST be public, i.e.
Account::is_publicreturnstrue. The network needs to read account storage to identify the account and route notes to it, so private accounts cannot be network accounts. - Its storage MUST contain a valid
NetworkAccountNoteAllowlistslot. Concretely:- the storage slot named
NetworkAccountNoteAllowlist::slot_nameMUST be present, - the slot MUST be a
StorageMap(not a value slot), - the map MUST be non-empty (the allowlist contains at least one allowed
NoteScriptRoot).
- the storage slot named
- Its storage MUST contain a
NetworkAccountTxScriptAllowlistslot, and the slot (aStorageMap) MUST contain the root of the canonicalExpirationTransactionScript. The network transaction builder attaches that script to every network transaction it executes, so an account without the root could never be serviced.
The allowlist slots are the shared abstraction across every network-account component: they let
off-chain services identify a network account without knowing which component it uses.
NetworkAccount::builder produces accounts satisfying this specification by construction.
Implementations§
Source§impl NetworkAccount
impl NetworkAccount
Sourcepub fn new(account: Account) -> Result<NetworkAccount, NetworkAccountError>
pub fn new(account: Account) -> Result<NetworkAccount, NetworkAccountError>
Attempts to construct a NetworkAccount from account.
Returns an error if:
- the account is not
public, or - the account’s storage does not contain a valid
NetworkAccountNoteAllowlistslot (seeNetworkAccountNoteAllowlist::try_fromfor the exact storage-level checks), or - the account’s storage does not contain a valid
NetworkAccountTxScriptAllowlistslot, or the allowlist does not contain the canonicalExpirationTransactionScriptroot.
Sourcepub fn builder(
init_seed: [u8; 32],
allowed_notes: BTreeSet<NoteScriptRoot>,
) -> Result<AccountBuilder, NetworkAccountNoteAllowlistError>
pub fn builder( init_seed: [u8; 32], allowed_notes: BTreeSet<NoteScriptRoot>, ) -> Result<AccountBuilder, NetworkAccountNoteAllowlistError>
Creates an AccountBuilder pre-configured as a network account.
The returned builder is set to AccountType::Public and has the AuthNetworkAccount
auth component installed with the provided note allowlist. The component’s tx-script
allowlist contains the canonical ExpirationTransactionScript, which the network
transaction builder attaches to every network transaction it executes, so the built
account is serviceable by the network by construction.
Callers add their functional components to the returned builder and finish with
AccountBuilder::build; the built account satisfies the NetworkAccount
specification. Accounts that need to allowlist additional transaction scripts should
construct the AuthNetworkAccount component manually instead.
§Errors
Returns an error if allowed_notes is empty since the account could not consume any
notes.
Sourcepub fn into_account(self) -> Account
pub fn into_account(self) -> Account
Consumes self and returns the underlying Account.
Sourcepub fn as_account(&self) -> &Account
pub fn as_account(&self) -> &Account
Returns a reference to the underlying Account.
Sourcepub fn storage(&self) -> &AccountStorage
pub fn storage(&self) -> &AccountStorage
Returns a reference to the AccountStorage of the underlying account.
Sourcepub fn allowed_notes(&self) -> &NetworkAccountNoteAllowlist
pub fn allowed_notes(&self) -> &NetworkAccountNoteAllowlist
Returns the NetworkAccountNoteAllowlist decoded from the underlying account’s storage.
Sourcepub fn allowed_tx_scripts(&self) -> &NetworkAccountTxScriptAllowlist
pub fn allowed_tx_scripts(&self) -> &NetworkAccountTxScriptAllowlist
Returns the NetworkAccountTxScriptAllowlist decoded from the underlying account’s
storage. It always contains at least the canonical ExpirationTransactionScript root.
Sourcepub fn allows_tx_script(&self, root: &TransactionScriptRoot) -> bool
pub fn allows_tx_script(&self, root: &TransactionScriptRoot) -> bool
Returns true if the account allowlists the transaction script with the given root.
A transaction executed against this account that carries a transaction script whose root is not allowlisted is rejected by the account’s auth procedure.

fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to

This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.

Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example

wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():

👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().

Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
