Struct merino_web::errors::HandlerError

source · [−]

pub struct HandlerError {
    kind: HandlerErrorKind,
    pub(crate) backtrace: Backtrace,
}

Expand description

The Standard Error for most of Merino

Fields

kind: HandlerErrorKind

The wrapped error value.

backtrace: Backtrace

The backtrace related to the wrapped error.

Implementations

source

impl HandlerError

source

pub fn kind(&self) -> &HandlerErrorKind

Access the wrapped error.

source

pub fn internal() -> Self

Get an HandlerError representing an Internal error.

This is a convenience function: the same result can be achieved by directly using HandlerErrorKind::Internal.into().

1.0.0 · source

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
