Why an HTTP transfer failed.

Variants

ClientInit(String)

The platform could not create its HTTP client. The text describes the cause.

RequestFailed

The request could not be sent or got no response.

Fields

url: String

The URL that was requested.

message: String

What the platform reported.

HttpStatus

The server answered with a status outside the 2xx range.

Fields

url: String

The URL that was requested.

status: u16

The status code of the response.

BodyReadFailed

The response body ended early or could not be read.

Fields

url: String

The URL that was requested.

message: String

What the platform reported.

InvalidResponse

The response is not usable, such as a body that is not valid UTF-8 text.

Fields

url: String

The URL that was requested.

message: String

What is wrong with the response.

NoWindow

The browser gave no window object to send the request through.

WorkerPanicked

A worker thread that ran part of the operation panicked.

Fields

operation: &'static str

The operation that the worker thread ran.

UnsupportedFeature

The operation needs a cranpose-services feature that is turned off.

Fields

operation: &'static str

The operation that the build cannot run.

feature: &'static str

Name of the cranpose-services feature that the operation needs.

Cancelled

The caller cancelled the transfer through its HttpControl.

FileWrite

A downloaded file could not be written to disk.

Fields

path: String

The path of the file that failed to write.

kind: ErrorKind

What the system reported, such as std::io::ErrorKind::StorageFull for a full disk.

message: String

The text of the system error.

Trait Implementations

impl Clone for HttpError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HttpError

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

Formats the value using the given formatter.

impl Display for HttpError

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

Formats the value using the given formatter.

impl Error for HttpError

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.
