Enum HttpStackError 

#[non_exhaustive]
pub enum HttpStackError {
    Transport(BoxError),
    Timeout {
        phase: TimeoutPhase,
    },
    Config {
        hint: String,
    },
    ProxyConnect {
        hint: String,
    },
}

HTTP stack-layer error.

Corresponds to the E in toac::CallError<E> — the provider translates this error into ProviderErrorKind in call_error_to_provider (see HTTP retry/error semantics).

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.

Transport(BoxError)

Transport error (DNS, TCP, TLS, hyper I/O, etc.).

Timeout

Request timed out. phase indicates which stage timed out — currently only supports Total. Staged timeouts for HTTP requests.

Fields

phase: TimeoutPhase

Config

HTTP layer configuration error (e.g., proxy URL parsing failure).

Fields

hint: String

ProxyConnect

Proxy CONNECT phase failed.

Fields

hint: String

Trait Implementations

impl Debug for HttpStackError

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

Formats the value using the given formatter.

impl Display for HttpStackError

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

Formats the value using the given formatter.

impl Error for HttpStackError

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.
