Enum HarnessError 

#[non_exhaustive]
pub enum HarnessError {
    NoClientTransaction,
    NoInvitation,
    InvalidStatus(u16),
    Build(BuildError),
    EndpointClosed,
    Call(Error),
    DialTask,
    DialBeforeInvitation,
    MissingAck,
    Transport(Error),
}

A call harness operation that could not be performed.

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.

NoClientTransaction

The request cannot create a client transaction (for example, it is an ACK).

NoInvitation

No INVITE has reached the answering side yet.

InvalidStatus(u16)

An answer helper was asked to use a status outside SIP’s status range.

Build(BuildError)

The response could not safely be built from the invitation.

EndpointClosed

The in-process endpoint closed before the exchange completed.

Call(Error)

The call framework rejected or could not establish the exchange.

DialTask

The dial task ended without returning its call result.

DialBeforeInvitation

The dial completed without ever delivering its invitation to the peer.

MissingAck

The request following the answer was not the dialog’s ACK.

Transport(Error)

The signalling harness could not construct its transport boundary.

Trait Implementations

impl Debug for HarnessError

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

Formats the value using the given formatter.

impl Display for HarnessError

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

Formats the value using the given formatter.

impl Error for HarnessError

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.
