Enum ServerError 

#[non_exhaustive]
pub enum ServerError {
    InvalidAddress {
        address: String,
        reason: String,
    },
    Bind {
        address: String,
        source: Error,
    },
    NestedRuntime,
    Runtime(Error),
    Io(Error),
}

Errors raised while starting or running the HTTP server (as opposed to errors produced while handling a request).

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.

InvalidAddress

The listen address could not be parsed or resolved.

Fields

address: String

The address as given.

reason: String

Why it was rejected.

Bind

Binding the TCP listener failed (address in use, permission denied…).

Fields

address: String

The address that could not be bound.

source: Error

The underlying I/O error.

NestedRuntime

run_blocking was called from inside an active Tokio runtime.

Runtime(Error)

The Tokio runtime could not be created.

Io(Error)

An I/O error occurred on the listening socket.

Trait Implementations

impl Debug for ServerError

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

Formats the value using the given formatter.

impl Display for ServerError

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

Formats the value using the given formatter.

impl Error for ServerError

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 ServerError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ServerError> for Error

fn from(err: ServerError) -> Self

Converts to this type from the input type.
