Struct Whitelist 

#[repr(C)]
pub struct Whitelist {
    pub code_hash: [u8; 32],
    pub usage_count: u64,
}

Whitelist tracks access codes for pre-mine phase. Each code can be used by multiple wallets - codes are shared. PDA includes only code_hash (not tied to specific wallets).

Fields

code_hash: [u8; 32]

The code hash (first 32 bytes of keccak256 hash of the code string)

usage_count: u64

Number of times this code has been used (optional tracking)

Implementations

impl Whitelist

pub fn pda(code_hash: [u8; 32]) -> (Pubkey, u8)

Derives the PDA for a Whitelist account. PDA seeds: [b“whitelist“, code_hash] This allows the same code to be used by multiple wallets.

pub fn validate_premine_code<'a>( is_premine: bool, has_access_code: bool, access_code_hash: [u8; 32], whitelist_info_opt: Option<&AccountInfo<'a>>, ) -> Result<(), ProgramError>

Validates and processes a premine access code for a new transaction.

This function:

• Requires access code if pre-mine is active
• Validates the code account exists and matches the provided hash
• Increments the code’s usage count
• Ignores access code if pre-mine is not active (not an error)

Returns Ok(()) if validation passes or code is ignored, Err if validation fails.

impl Whitelist

pub fn to_bytes(&self) -> &[u8]

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

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

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

impl Clone for Whitelist

fn clone(&self) -> Whitelist

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Whitelist

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Whitelist

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Discriminator for Whitelist

fn discriminator() -> u8

impl PartialEq for Whitelist

fn eq(&self, other: &Whitelist) -> 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 Whitelist

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 Whitelist

fn zeroed() -> Self

Calls zeroed.

impl Copy for Whitelist
