* Crates
Error-handling crates seem to rise and fall pretty regularly, each new
crate leveraging new primitives in the standard library to push
ergonomics even further:

- error_chain
- failure
- snafu
- thiserror
- anyhow
- eyre
* Ongoing development
Error handling now has a [[https://github.com/rust-lang/project-error-handling][dedicated project group]] under the [[https://www.rust-lang.org/governance/teams/library][library
team]].
