Silence reqwest debug/trace level logging

[aress31]

Hi, it has been a while now that I am trying to find a way to silence reqwest, I handle the logging myself and as such am not interested in reqwest default logging for debug/trace levels, see:

17:36:35 [DEBUG] (2) reqwest::connect: starting new connection: https://login.microsoft.com/
17:36:35 [DEBUG] (2) reqwest::async_impl::client: response '400 Bad Request' for https://login.microsoft.com/common/oauth2/token
17:36:35 [DEBUG] (1) raadef: [1/30] (MSGraphApi) REDACTED@contosco:REDACTED -> INVALID_TENANT (AADSTS900023)
17:36:37 [DEBUG] (2) reqwest::async_impl::client: response '400 Bad Request' for https://login.microsoft.com/common/oauth2/token
17:36:37 [DEBUG] (1) raadef: [2/30] (MSGraphApi) REDACTED@contosco:REDACTED -> INVALID_TENANT (AADSTS900023)

How could I please silence the output?

This depends on what your logging setup is like. If you're using env_logger for instance, you probably have the RUST_LOG environment set to trace, which will simply enable all trace logs from all crates. If you want to restrict reqwest to info and above, you can just set RUST_LOG=trace,reqwest=info which will set all crates to trace level, except for reqwest which will be at the info level. But again, depends on how your logging setup is like.

@Victor-N-Suadicani, my setup is pretty basic, I simply rely on the simplelog lib, see:

use simplelog::{
    debug, error, info, trace, ColorChoice, CombinedLogger, Config, TermLogger, TerminalMode,
    WriteLogger,
};

--- SNIP ---

    let _ = CombinedLogger::init(vec![
        TermLogger::new(
            args.verbose.log_level_filter(),
            Config::default(),
            TerminalMode::Stdout,
            ColorChoice::Auto,
        ),
        WriteLogger::new(
            args.verbose.log_level_filter(),
            Config::default(),
            File::create(args.outfile.clone()).unwrap(),
        ),
    ]);

    debug!("CLI arguments: {:#?}", args);

And then manually format my output, that is why I would like to totally silence reqwest.

[Victor-N-Suadicani]

A quick search on simplelog's documentation and I found the add_filter_ignore method on the ConfigBuilder struct. You should probably use that to create your log configs instead of doing Config::default().

In any case, you should probably ask in simplelog's repository, this is more of a simplelog question than it is a reqwest question :)

Drakulix/simplelog.rs#107 <- will see if that help, thanks for putting me to the right path @Victor-N-Suadicani !

For anyone using env_logger, you can silence reqwest to whatever degree you like using the filter_module builder method

Example

let mut log_builder = Builder::new();
log_builder
    .filter(None, LevelFilter::Info) // log level for your module
    .filter_module("reqwest", LevelFilter::Off)  // log level for reqwest
    .init();
