Enum ErrorCode 

Source 
#[non_exhaustive]
pub enum ErrorCode {
    BadRequest,

    InsufficientLiquidity,
    SolveTimeout,
    ServiceUnavailable,
    ServerError,
    NotFound,
    Unknown(String),
}
Expand description

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)§

This enum is marked as 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§

Source§

impl ErrorCode

Source

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.

Source

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.
