Enum QuoteError 

pub enum QuoteError {
    EmptyReserves,
    BaseOutExceedsReserve,
    FeesExceedOutput,
    DepletedBondingCurve,
    MathOverflow,
    SlippageExceeded,
}

Reasons a quote computation can fail. Returned in place of a panic for any case where the inputs are inconsistent with a well-formed pool or trade — empty reserves, oversized requests, or fee configurations whose total bps would consume the entire trade.

Variants

EmptyReserves

base_reserve or quote_reserve is zero, so the pool cannot price any trade.

BaseOutExceedsReserve

Caller asked for base_out >= base_reserve on a buy. Equivalent to draining the pool; the constant-product denominator would be <= 0.

FeesExceedOutput

Sum of LP, protocol, and coin-creator fees exceeds the raw quote output — only reachable with a degenerate fee table whose total bps

10_000.

DepletedBondingCurve

Bonding curve degeneracy where real_token_reserves == virtual_token_reserves, which would zero the constant-product denominator on a token-out buy.

MathOverflow

A u128 intermediate overflowed, or a subtraction would underflow (e.g. sol_out >= virtual_sol_reserves on the sell_token_quote_with_sol inverse). Surfaced from the fee-less primitive quote helpers so callers don’t need to wrap primitive arithmetic.

SlippageExceeded

Observed market cap fell outside the caller’s target ± slippage_bps envelope. Returned by validate_market_cap on both quote paths.

Trait Implementations

impl Clone for QuoteError

fn clone(&self) -> QuoteError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuoteError

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

Formats the value using the given formatter.

impl Display for QuoteError

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

Formats the value using the given formatter.

impl Error for QuoteError

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 QuoteError

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