Enum ErrorCode 

#[non_exhaustive]
pub enum ErrorCode {
    BadRequest,
    NoRouteFound,
    InsufficientLiquidity,
    SolveTimeout,
    ServiceUnavailable,
    ServerError,
    NotFound,
    Unknown(String),
}

A structured error code returned by the Fynd RPC API.

Mapped from the raw string code field in fynd_rpc_types::ErrorResponse.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BadRequest

The request was malformed or contained invalid parameters.

Server codes: BAD_REQUEST, INVALID_ORDER.

NoRouteFound

No swap route exists between the requested token pair.

Server code: NO_ROUTE_FOUND.

InsufficientLiquidity

A route exists but available pool liquidity is too shallow for the requested amount.

Server code: INSUFFICIENT_LIQUIDITY.

SolveTimeout

The solver timed out before returning a route. Retrying may succeed.

Server code: TIMEOUT.

ServiceUnavailable

The server is temporarily unavailable (overloaded, queue full, stale data, or not yet initialised). Retrying after a short backoff should succeed.

Server codes: QUEUE_FULL, SERVICE_OVERLOADED, STALE_DATA, NOT_READY.

ServerError

The server encountered an internal error processing the request. Not retryable.

Server codes: ALGORITHM_ERROR, INTERNAL_ERROR, FAILED_ENCODING.

NotFound

The requested endpoint does not exist. Indicates a client misconfiguration.

Server code: NOT_FOUND.

Unknown(String)

A truly unrecognised server error code. The raw string is preserved for debugging.

Implementations

impl ErrorCode

pub fn from_server_code(code: &str) -> Self

Map a raw server error code string to a typed ErrorCode.

Unknown codes are wrapped in ErrorCode::Unknown rather than panicking.

pub fn is_retryable(&self) -> bool

Returns true if this error code indicates that the request is safe to retry.

Only SolveTimeout and ServiceUnavailable are retryable; all other codes represent permanent failures.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl PartialEq for ErrorCode

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