Implementations

impl Error

pub fn is_network_permanently_blocked(&self) -> bool

Returns true if this network/fetch error indicates a permanent/blocking condition that won’t be resolved by retrying (e.g., DNS failure, connection refused, blocked endpoint). Returns false for transient errors worth retrying (timeouts, rate limits, server errors).

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<SystemTimeError> for Error

fn from(source: SystemTimeError) -> Self

Converts to this type from the input type.
