feat: replace std::time with web_time for wasm32-unknown-unknown compatibility

[Dicklessgreat]

This pull request updates the reqwest-retry crate to replace the usage of std::time with the web-time crate for handling time-related functionality. This change ensures compatibility with WebAssembly (WASM) environments, where std::time is not supported. The modifications span dependency updates, source code adjustments, and test updates.

Dependency Update:

• reqwest-retry/Cargo.toml: Added web-time = "1.1.0" as a dependency to replace std::time.

Code Changes:

• reqwest-retry/src/middleware.rs: Replaced imports of std::time::{Duration, SystemTime} with web_time::{Duration, SystemTime} across the middleware implementation.
• macro_rules! log_retry in reqwest-retry/src/middleware.rs: Updated example code comments to use web_time::Duration instead of std::time::Duration.

Test Updates:

• reqwest-retry/tests/all/retry.rs:
  • Replaced std::time::Duration with web_time::Duration in multiple test functions (assert_retry_succeeds_inner, assert_retry_on_request_timeout, assert_retry_on_incomplete_message, assert_retry_on_hyper_canceled, assert_retry_on_connection_reset_by_peer). This ensures compatibility with the new dependency. [1] [2] [3] [4] [5] [6] [7]
  • Updated the RetryTimeoutResponder struct and its new method to use web_time::Duration instead of std::time::Duration.

It works on my machine

I have already tested that this fix works on my project, by refering git url and rev hash directly.
