Implementations

impl BudgetExpr

pub fn new_payment(lamports: u64, to: &Pubkey) -> Self

Create the simplest budget - one that pays lamports to Pubkey.

pub fn new_authorized_payment(from: &Pubkey, lamports: u64, to: &Pubkey) -> Self

Create a budget that pays lamports to to after being witnessed by from.

pub fn new_payment_when_account_data( account_pubkey: &Pubkey, account_program_id: &Pubkey, account_hash: Hash, lamports: u64, to: &Pubkey, ) -> Self

Create a budget that pays lamports to to after witnessing account data in account_pubkey with the given hash.

pub fn new_cancelable_authorized_payment( witness: &Pubkey, lamports: u64, to: &Pubkey, from: Option<Pubkey>, ) -> Self

Create a budget that pays lamports to to after being witnessed by witness unless canceled with a signature from from.

pub fn new_2_2_multisig_payment( from0: &Pubkey, from1: &Pubkey, lamports: u64, to: &Pubkey, ) -> Self

Create a budget that pays lamportstotoafter being witnessed by 2xfrom`s

pub fn new_future_payment( dt: DateTime<Utc>, dt_pubkey: &Pubkey, lamports: u64, to: &Pubkey, ) -> Self

Create a budget that pays lamports to to after the given DateTime signed by dt_pubkey.

pub fn new_cancelable_future_payment( dt: DateTime<Utc>, dt_pubkey: &Pubkey, lamports: u64, to: &Pubkey, from: Option<Pubkey>, ) -> Self

Create a budget that pays lamports to to after the given DateTime signed by dt_pubkey unless canceled by from.

pub fn final_payment(&self) -> Option<Payment>

Return Payment if the budget requires no additional Witnesses.

pub fn verify(&self, spendable_lamports: u64) -> bool

Return true if the budget spends exactly spendable_lamports.

pub fn apply_witness(&mut self, witness: &Witness, from: &Pubkey)

Apply a witness to the budget to see if the budget can be reduced. If so, modify the budget in-place.

Trait Implementations

impl Clone for BudgetExpr

fn clone(&self) -> BudgetExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BudgetExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BudgetExpr

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BudgetExpr

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