Struct Code 

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

Code tracks access codes for pre-mine phase. Each code is linked to a specific wallet (authority) to prevent abuse. One code per wallet - PDA includes both code_hash and authority.

Fields

code_hash: [u8; 32]

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

authority: Pubkey

The wallet (authority) this code is linked to

usage_count: u64

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

Implementations

impl Code

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

Derives the PDA for a Code account. PDA seeds: [b“premine_code“, code_hash, authority.to_bytes()] This ensures one code per wallet (same code_hash + different authority = different PDA)

impl Code

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

Trait Implementations

impl AccountValidation for Code

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

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

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<F>(&mut self, condition: F) -> Result<&mut Self, ProgramError>

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

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

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

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

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

impl Clone for Code

fn clone(&self) -> Code

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Code

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Code

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Discriminator for Code

fn discriminator() -> u8

impl PartialEq for Code

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

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 Code

fn zeroed() -> Self

Calls zeroed.

impl Copy for Code

impl Pod for Code

impl StructuralPartialEq for Code
