Mystified about strings? Borrow checker have you in a headlock? Seek help here! There are no stupid questions, only docs that haven't been written yet. Please note that if you include code examples to e.g. show a compiler error or surprising result, linking a playground with the code will improve your chances of getting help quickly.

• cargo-make

  Rust task runner and build tool.

You might be interested in cargo-make, which is based on TOML, or Just, which has a syntax that is vaguely inspired by Make but much less weird sigils and more suited to non-file-based tasks.

  Concise, consistent, and legible badges in SVG and raster format

  

I just read the above article by the official rust blog. I wanted to ask what is "feature" and "badge" refered to as in this blog? what does it mean? At some places "shields.io badge " is mentioned. Are "badge" and "feature" some rust terminologies? It will be helpful if someone explains me this blog post in fewer words.

  RFCs for changes to Rust

  

The only ways to convert float to int right now are using "as", or the unsafe "to_int_unchecked" methods defined for the floating point types. There's an open feature request for "to_int_checked" methods, but it looks like it was posted and only had a couple days of comments without any agreement on what the final semantics would look like: https://github.com/rust-lang/rfcs/issues/3304

  Apache OpenDAL: access data freely.

  

[profiles.mys3] type = "s3" region = "us-east-1" access_key_id = "foo" enable_virtual_host_style = "on" ``` The team at Opendal wrote a handcrafting config parser for the same use case, see. Since parsing configs in toml or json is a standard functionality, is there any recommended way?

• twelf

  1 104 6.0 Rust

  Twelf is a configuration solution for Rust including 12-Factor support. It is designed with layers in order to configure different sources and formats to build your configuration. The main goal is to be very simple using a proc macro.

Thank you, I thought about this one. The challenge with config.rs it doesn't support lists and hashes in environment variables. I found a crate which does exactly what I need Twelf - surprisingly unpopular.
