Enum FetchError 

pub enum FetchError {
    Network(String),
    Abort(String),
    Timeout(String),
    TooManyRedirects(u32),
    RedirectRefused(String),
    Blocked(String),
    Denied(Denied),
    InvalidUrl(String),
    Body(String),
    Bridge(String),
}

A fetch engine failure.

Variants

Network(String)

A transport failure (connection refused, reset past the retry budget, TLS error, DNS). WHATWG surfaces this as TypeError.

Abort(String)

The request’s AbortSignal fired.

Timeout(String)

The per-request timeout elapsed.

TooManyRedirects(u32)

redirect: follow exceeded the redirect budget.

RedirectRefused(String)

redirect: error saw a 3xx, or a redirect target had no Location that could be resolved.

Blocked(String)

The sandbox network guard denied the URL or a resolved address.

Denied(Denied)

The realm’s net grant refused the host. Kept typed so a runtime can throw it as the permission error it is.

InvalidUrl(String)

A URL could not be parsed / resolved against the base URL.

Body(String)

The response body could not be read.

Bridge(String)

The host-owned cookie jar or defaults could not be read or written (see crate::ContextBridge).

Trait Implementations

impl Debug for FetchError

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

Formats the value using the given formatter.

impl Display for FetchError

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

Formats the value using the given formatter.

impl Error for FetchError

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<GuardError> for FetchError

fn from(e: GuardError) -> Self

Converts to this type from the input type.
