Implementations

impl BudgetExpr

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

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

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

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

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

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

pub fn new_future_payment(
    dt: DateTime<Utc>,
    from: Pubkey,
    tokens: u64,
    to: Pubkey
) -> Self

Create a budget that pays tokens to to after the given DateTime.

pub fn new_cancelable_future_payment(
    dt: DateTime<Utc>,
    from: Pubkey,
    tokens: u64,
    to: Pubkey
) -> Self

Create a budget that pays tokens to to after the given DateTime unless cancelled by from.

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

Return Payment if the budget requires no additional Witnesses.

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

Return true if the budget spends exactly spendable_tokens.

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 copy 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<BudgetExpr> for BudgetExpr

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BudgetExpr

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.
