google_cloud_storage::read_resume_policy

Struct Recommended

pub struct Recommended;

Expand description

The recommended policy when reading objects from Cloud Storage.

This policy resumes any read that fails due to I/O errors, and stops on any other error kind.

§Example

let policy = Recommended;
assert!(matches!(policy.on_error(&ResumeQuery::new(0), io_error()), ResumeResult::Continue(_)));
assert!(matches!(policy.on_error(&ResumeQuery::new(0), other_error()), ResumeResult::Permanent(_)));

use gax::error::{Error, rpc::Code, rpc::Status};
fn io_error() -> Error {
   // ... details omitted ...
}
fn other_error() -> Error {
   // ... details omitted ...
}
