Why inherited descriptors were refused.

assert_eq!(net_io::InheritError::BadCount.to_string(), "LISTEN_FDS is not a valid count");

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.

BadCount

LISTEN_FDS is not a non-negative number.

TooMany

More descriptors than allowed.

Fields

max: u32

The maximum.

NotASocket

The descriptor is not a socket.

Fields

fd: i32

The descriptor.

NotListening

The socket is not listening.

Fields

fd: i32

The descriptor.

WrongKind

The socket’s family or type is not one net-io serves.

Fields

fd: i32

The descriptor.

NamesMismatch

LISTEN_FDNAMES does not match LISTEN_FDS.

PidFdMismatch

LISTEN_PIDFDID does not match this process.

Os(Error)

An OS call failed.

Trait Implementations

impl Debug for InheritError

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

Formats the value using the given formatter.

impl Display for InheritError

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

Formats the value using the given formatter.

impl Error for InheritError

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.
