Implementations

impl Stake

pub fn pda(&self) -> (Pubkey, u8)

pub fn calculate_multiplier(lock_duration_days: u64) -> f64

Calculate lock multiplier based on duration (Magic Eden formula)

pub fn score(&self) -> u64

Calculate score (balance * multiplier)

pub fn is_locked(&self, clock: &Clock) -> bool

Check if stake is currently locked

pub fn remaining_lock_seconds(&self, clock: &Clock) -> u64

Trait Implementations

impl AccountValidation for Stake

fn assert_err<F>( &self, condition: F, err: ProgramError, ) -> Result<&Self, ProgramError>

where F: Fn(&Self) -> bool,

fn assert_msg<F>(&self, condition: F, msg: &str) -> Result<&Self, ProgramError>

where F: Fn(&Self) -> bool,

fn assert_mut_msg<F>( &mut self, condition: F, msg: &str, ) -> Result<&mut Self, ProgramError>

impl Clone for Stake

fn clone(&self) -> Stake

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stake

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Stake

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Discriminator for Stake

fn discriminator() -> u8

impl PartialEq for Stake

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

impl Serialize for Stake

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Zeroable for Stake

fn zeroed() -> Self

Calls zeroed.

impl Copy for Stake

impl Pod for Stake

impl StructuralPartialEq for Stake
