Struct grid_sdk::error::ResourceTemporarilyUnavailableError

pub struct ResourceTemporarilyUnavailableError { /* fields omitted */ }

An error which is returned when an underlying resource is unavailable.

This error can be handled by retrying, usually in a loop with a small delay.

Implementations

impl ResourceTemporarilyUnavailableError

pub fn from_source(source: Box<dyn Error>) -> Self

Constructs a new ResourceTemporarilyUnavailableError from a specified source error.

The implementation of std::fmt::Display for this error will simply pass through the display of the source message unmodified.

Examples

use grid_sdk::error::ResourceTemporarilyUnavailableError;

let io_err = std::io::Error::new(std::io::ErrorKind::Other, "io error");
let rtu_error = ResourceTemporarilyUnavailableError::from_source(Box::new(io_err));
assert_eq!(format!("{}", rtu_error), "io error");

pub fn from_source_with_hint(
    source: Box<dyn Error>,
    retry_duration_hint: Duration
) -> Self

Constructs a new ResourceTemporarilyUnavailableError from a specified source error with a retry duration hint.

The hint specified here can be used by the caller as the duration between retry attempts. Callers may ignore this hint and provide their own algorithms, or may use this Duration as provided.

The implementation of std::fmt::Display for this error will simply pass through the display of the source message unmodified.

Examples

use std::time::Duration;

use grid_sdk::error::ResourceTemporarilyUnavailableError;

let io_err = std::io::Error::new(std::io::ErrorKind::Other, "io error");
let rtu_error = ResourceTemporarilyUnavailableError::from_source_with_hint(Box::new(io_err), Duration::new(10, 0));
assert_eq!(format!("{}", rtu_error), "io error");

pub fn retry_duration_hint(&self) -> Option<Duration>

Returns the duration which the underlying library provides as a suggestion for an appropriate amount of time between retry attempts.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
