Errors from build_pool.

Variants

MissingField

A required field is missing for this variant.

Fields

variant: CurveVariant

field: &'static str

WrongCoinCount

The number of balances doesn’t match the expected coin count.

Fields

variant: CurveVariant

expected: usize

actual: usize

DecimalsMismatch

Token decimals length doesn’t match balances length.

Fields

balances_len: usize

decimals_len: usize

DecimalsTooLarge

Token decimals exceed the maximum (18 for CryptoSwap, 36 for StableSwap).

Fields

index: usize

decimals: u8

max: u8

DynamicRatesMismatch

Dynamic rates length doesn’t match balances length.

Fields

balances_len: usize

rates_len: usize

PriceScaleWrongLen

Price scale has wrong number of elements.

Fields

expected: usize

actual: usize

MetaMissingVirtualPrice

StableSwapMeta requires dynamic_rates with an explicit rate for the base pool LP token (last coin). Without it, rates[N-1] defaults to 10^(36-decimals) which is incorrect — it must be base_pool.get_virtual_price().

Trait Implementations

impl Clone for BuildError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuildError

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

Formats the value using the given formatter.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Eq for BuildError

impl Error for BuildError

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 BuildError

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

Equality operator ==.

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

Inequality operator !=.
