Struct ResourceContract 

pub struct ResourceContract {
    pub task_id_hash: u64,
    pub token_ceiling: u64,
    pub cycles_remaining: u64,
    pub tokens_burned: u64,
}

The live resource contract + hardware circuit breakers a granted task runs under (established by 0x71). Deterministic, zero-heap.

Fields

task_id_hash: u64

token_ceiling: u64

Declared token ceiling — the anti-usury bound for Self::burn_tokens.

cycles_remaining: u64

Decrementing clock-cycle breaker.

tokens_burned: u64

Summation tracker of tokens burned so far.

Implementations

impl ResourceContract

pub fn tick_cycles(&mut self, n: u64) -> bool

Charge n clock cycles against the decrementing breaker. Returns false (breaker tripped) when the budget would underflow — the caller must halt the task.

pub fn burn_tokens(&mut self, n: u64) -> Result<(), UsuryError>

Add n to the token-burn tracker. Err(UsuryError) once the cumulative burn breaches the usury ceiling (declared ceiling + the default overage) — the anti-usury layer.

Trait Implementations

impl Clone for ResourceContract

fn clone(&self) -> ResourceContract

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResourceContract

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

Formats the value using the given formatter.

impl PartialEq for ResourceContract

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