Errors produced while encoding, decoding, or transporting TWS API frames.

Variants

NonPrintableAscii(String)

A caller attempted to encode a value containing non-printable ASCII.

MissingField

A caller attempted to send a missing field value.

FrameTooLarge(u32)

A frame length prefix exceeded the supported platform size.

IncompleteFrame

A message was incomplete.

Fields

needed: usize

Number of bytes needed to finish the frame.

available: usize

Number of bytes currently available.

MalformedHandshake

The peer returned a malformed handshake response.

UnsupportedServerVersion

The peer advertised an unsupported server version.

Fields

server_version: i32

Advertised server version.

min_version: i32

Required minimum version.

UnsupportedRequestParameter

A request used a field that the negotiated server version does not support.

Fields

server_version: i32

Advertised server version.

min_version: i32

Required minimum version.

parameter: &'static str

Unsupported parameter name.

Io(Error)

A network operation failed.

InvalidInteger

An integer field could not be parsed.

Fields

field: String

Field content.

source: ParseIntError

Parse failure.

InvalidDecimal

A decimal field could not be parsed.

Fields

field: String

Field content.

source: Error

Trait Implementations

impl Debug for TwsApiError

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

Formats the value using the given formatter.

impl Display for TwsApiError

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

Formats the value using the given formatter.

impl Error for TwsApiError

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 From<DecodeError> for TwsApiError

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl From<Error> for TwsApiError

fn from(source: Error) -> Self

Converts to this type from the input type.
