Other similar libraries

[jayvdb]

I have seen a few libraries doing similar. It would be good to collate a list of them, and then add them to the readme.

Probably the main criteria is being able to support nested structures.

softprops/envy#26 & softprops/envy#55 - still open issues in envy, and softprops/envy#52 is a PR regarding supporting hashmap & available at fork https://github.com/bnjjj/envy.

https://github.com/SergioBenitez/Figment supports multiple sources of config, with an env provider that supports arrays & mappings.

[jayvdb]

https://github.com/TheNeikos/envious - env only, very similar to serde-env

[jayvdb]

Two more

• https://github.com/moonrepo/schematic
• https://github.com/bnjjj/twelf uses envy , but uses the fork https://github.com/bnjjj/envy with hashmap support

[jayvdb]

A bit off-topic, https://github.com/withoutboats/configure is very old and now unmaintained, and likely doesnt support nesting, but is notable for being very early in the attempts to do "12-factor" in Rust.

https://github.com/sagiegurari/envmnt - not serde, and not nested, but a good collection of low level functions to manage environment variables

uses serde, but not investigated deeper
