Changelog envious

v0.3.0

Breaking change: Although no code will fail to compile, the following change may break assumptions on current behaviour:

• Arrays read from environment variables will now be sorted by those keys. This first tries to sort them numerically, then lexographically with the remaining key data. i.e.

  // Env variables:
  // config_array__a=a
  // config_array__1=1
  // config_array__1b=1b
  // config_array__2a=2a
  let config = ...;
  assert_eq!(config, Config { array: vec!["a" "1", "1b", "2a"]});

• Add a new Config setting to disable this new behaviour (but enable it anyway as it's probably the behaviour most people want).

v0.2.1

The 0.2.1 version fixes several unexpected behaviours w.r.t. case sensitivity:

• When case insensitive, environment variables with the same keys but different casing should be collated
  • i.e. previously database__password and DATABASE__username would have conflicted and only one the username or password would be read
• When case insensitive, the prefix is also treated insensitively

v0.2.0

The 0.2.0 version makes the following API changes:

• Config is the new entrypoint to envious, with all interactions happening via method calls.
• Case sensitivity is now configurable, see Config::case_sensitive
  • NB: The default is case insensitive, which is a change from the original behaviour.
• The separator is now configurable, using the same default as 0.1.x, see Config::with_separator
• Add from_iter allowing to deserialize from any source of (String, String) pairs

v0.1.1

The 0.1.1 version adds more and better documentation to the main readme.

v0.1.0

The 0.1.0 version is the initial public release of the envious crate.

Added:

• Initial implementation to deserialize structs with serde from environment variables
