Struct InstructionRule 

pub struct InstructionRule { /* private fields */ }

Rule that limits specific instruction types per wallet

Counts matching instructions in each transaction and enforces limits. Supports both lifetime limits (never resets) and time-windowed limits (resets periodically).

Currently supported instruction types:

• System: CreateAccount / CreateAccountWithSeed
• ATA: CreateIdempotent / Create

Implementations

impl InstructionRule

pub fn new( program: Pubkey, instruction: String, max: u64, window_seconds: Option<u64>, ) -> Self

pub fn lifetime(program: Pubkey, instruction: String, max: u64) -> Self

Create a lifetime instruction limit (never resets)

pub fn windowed( program: Pubkey, instruction: String, max: u64, window_seconds: u64, ) -> Self

Create a time-windowed instruction limit

pub fn count_all_rules( rules: &[&InstructionRule], ctx: &mut LimiterContext<'_>, ) -> Vec<u64>

Count matching instructions for one or more rules in a single pass Only counts instructions where Kora is the payer (subsidized operations)

pub fn storage_key(&self, user_id: &str, timestamp: u64) -> String

pub fn count_increment(&self, ctx: &mut LimiterContext<'_>) -> u64

How many units to increment for this transaction

pub fn max(&self) -> u64

Maximum allowed count within the window (or lifetime)

pub fn window_seconds(&self) -> Option<u64>

Time window in seconds

pub fn description(&self) -> String

Trait Implementations

impl Debug for InstructionRule

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

Formats the value using the given formatter.
