Enum Error 

pub enum Error {
    StreamAlreadyDone,
    StreamAlreadyClosed,
    SequenceError,
    InvalidRecordVersion,
    InvalidRoleNumber,
    UnknownRecordType(u16, u8),
    IoError(Error),
}

Errors that can be returned by calls to process.

Variants

StreamAlreadyDone

The input stream was already closed and can not be reused. This indicates an error within the call sequence, like calling process twice or the web-server sending more data after closing StdIn or Data.

StreamAlreadyClosed

write was called on an output stream that was already closed by a call to close.

SequenceError

The web-server violated the FastCGI specification. For example by sending a StdIn record before sending a BeginRequest record.

InvalidRecordVersion

The record version is not 1. This should never happen since the FastCGI specification does not define any other record versions.

InvalidRoleNumber

The web-server sent an unknown role number. This is most likely a bug in the FastCGI implementation of the web-server.

UnknownRecordType(u16, u8)

This error is never returned to the user of the library. It is internally handled by the tokio-fastcgi crate. The library returns a FCGI_UNKNOWN_TYPE record to the web-server.

IoError(Error)

An IoError occurred. Most likely the connection to the web-server got lost or was interrupted. Some I/O errors are handled by tokio-fastcgi. If the web-server closes the FastCGI connection after all requests have been processed no error is returned and the EOF error is just swallowed.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(io_error: Error) -> Self

Converts to this type from the input type.
