Enum RateError 

pub enum RateError {
    ZeroBytes,
    Underpayment {
        paid: U256,
        bytes: U256,
        rate_per_mb: u64,
        tolerance_bps: u64,
    },
    Overflow,
}

Failure modes for verify_rate.

Variants

ZeroBytes

Voucher delta included zero bytes — cannot be priced. The node should reject it before it advances lane state.

Underpayment

Effective rate is below the advertised rate by more than the configured tolerance. The node should pause the stream and (per ADR 003 §Voucher withholding) refuse further delivery.

Fields

paid: U256

The voucher’s amount delta.

bytes: U256

The voucher’s bytes delta, priced against that amount.

rate_per_mb: u64

The advertised per-MB rate the payment is judged against.

tolerance_bps: u64

Allowed shortfall, in basis points of the expected amount.

Overflow

Arithmetic would overflow U256. Will not occur for realistic values but surfaced as an error rather than panicking, per the workspace anti-panic policy.

Trait Implementations

impl Debug for RateError

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

Formats the value using the given formatter.

impl Display for RateError

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

Formats the value using the given formatter.

impl Eq for RateError

impl Error for RateError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for RateError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
