Struct cyclos_core::states::fee::FeeState

#[repr(packed)]
pub struct FeeState {
    pub bump: u8,
    pub fee: u32,
    pub tick_spacing: u16,
}

Stores a fee amount and tick spacing pair enabled by the protocol owner

A fee amount can never be removed, so this value should be hard coded or cached in the calling context

PDA of [FEE_SEED, fee]

Fields

bump: u8

Bump to identify PDA

fee: u32

The enabled fee, denominated in hundredths of a bip (10^-6)

tick_spacing: u16

The minimum number of ticks between initialized ticks for pools created with the given fee

Trait Implementations

impl AccountDeserialize for FeeState

fn try_deserialize(buf: &mut &[u8]) -> Result<Self>

Deserializes previously initialized account data. Should fail for all uninitialized accounts, where the bytes are zeroed. Implementations should be unique to a particular account type so that one can never successfully deserialize the data of one account type into another. For example, if the SPL token program were to implement this trait, it should be impossible to deserialize a Mint account into a token Account.

fn try_deserialize_unchecked(buf: &mut &[u8]) -> Result<Self>

Deserializes account data without checking the account discriminator. This should only be used on account initialization, when the bytes of the account are zeroed.

impl Clone for FeeState

fn clone(&self) -> FeeState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FeeState

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

Formats the value using the given formatter.

impl Default for FeeState

fn default() -> FeeState

Returns the “default value” for a type.

impl Discriminator for FeeState

fn discriminator() -> [u8; 8]

impl Owner for FeeState

fn owner() -> Pubkey

impl Zeroable for FeeState

fn zeroed() -> Self

Calls zeroed.

impl Copy for FeeState

impl Pod for FeeState

impl ZeroCopy for FeeState
