In RFC : Try-Catch Blocks, someone expressed concern over the discoverability of crates. To improve this situation, I suggested to have a "Crate of the Week" similar to TWIR's "Quote of the Week". To jump-start this, I'm hereby asking you folks for nominations. We seek crates that are useful, unsung and/or ubercool! @nasa42 Should we find a strong contender, I'd like to put a few lines on it in the next TWIR. If you like I can write them personally.

Warning: Self promotion ahead! cfg_aliases: A dependency-less macro for creating aliases that can be used in #[cfg] checks.

I'd like to nominate coercible_errors - a zero-cost abstraction over errors that may be either some actual error type or Infallible in associated types.

tco: TCO is a tail-call optimization library. It's a proof-of-concept attribute macro you can slap onto item functions to optimize them if they are in tail-calling format.

bottom: Yet another cross-platform graphical process/system monitor

runiq: An efficient way to filter duplicate lines from input, à la uniq

Cargo Workspace Manager A tool to manage your cargo workspace, inspired by Lerna. You can list all the crates in the workspace You can list all the changed crates in the workspace since the last git tag (or other git refs) You can release the changed crates in the workspaces by interactively bumping their version which also bumps this crates version in other crates in the workspace if this is being used as a dependency. You can publish the crates in the workspace automatically in the correct order.

apply: a tiny library for chaining free functions into method call chains. For example, ever wanted tuples to have a .map() equivalent? let second = (12, 20, 30).apply(|x| x.1) does the trick.

cargo-wipe Cargo subcommand that recursively finds and optionally wipes all "target" or "node_modules" folders that are found in the current path.

defer-drop: a newtype that defers object drops to a background thread.
