Enum Error

#[non_exhaustive]
pub enum Error {
    BadAddress(Error),
    BadDescriptor(ParseIntError),
    DescriptorOutOfRange(i32),
    DescriptorsMissing,
    UnsupportedScheme,
}

Errors while processing service listeners.

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.

BadAddress(Error)

Address cannot be parsed and did not resolve to a known domain

BadDescriptor(ParseIntError)

Descriptor value cannot be parsed to a number.

DescriptorOutOfRange(i32)

Descriptor value exceeds acceptable range.

DescriptorsMissing

Descriptor environment variable (LISTEN_FDS) is missing.

UnsupportedScheme

Specified URI scheme is not supported.

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<ParseIntError> for Error

fn from(error: ParseIntError) -> Self

Converts to this type from the input type.
