Enum Error 

#[non_exhaustive]
pub enum Error {
    EmptyAppId,
    EmptyNodes,
    InvalidNode(String),
    LoadFailed,
    HttpStatus {
        url: String,
        status: u16,
    },
    Request(Error),
    WebSocket(String),
    Protocol(Error),
    Cache(String),
    CacheEncryptDisabled,
}

Failures that can occur while configuring, loading, or connecting.

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.

EmptyAppId

app_id was empty or whitespace.

EmptyNodes

No usable server node URLs were provided.

InvalidNode(String)

A node URL could not be converted to a WebSocket endpoint.

LoadFailed

Every node failed and no local cache was available.

HttpStatus

The server returned a non-success HTTP status.

Fields

url: String

Request URL.

status: u16

HTTP status code.

Request(Error)

Underlying HTTP client error.

WebSocket(String)

WebSocket handshake or I/O failed.

Protocol(Error)

The configuration payload could not be decoded.

Cache(String)

Reading or writing the local cache file failed.

CacheEncryptDisabled

CacheOptions::encrypt is true, but the crate was built without the cache-encrypt feature.

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, __formatter: &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(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
