confik: v0.15.11

• Add a new helper MergingUnsetBuilder and trait MergingWithUnset, for aiding in building of custom Configuration implementations. See the docs on MergingWithUnset for a worked example.
• Fix serde_json::Value merge when the first parsed config doesn't have any value set.

confik: v0.15.9

• No significant changes since 0.15.8.

confik: v0.15.10

• Add #[confik(struct_default)] for struct fields: when no configuration data is present for that field, its value is taken from the same-named field on <Self as Default>::default(). Can be combined with #[confik(skip)] (in place of an explicit #[confik(default)]). Cannot be combined with #[confik(default)] on the same field, and is not supported on enum variant fields (the configuration type must remain a struct).
• Fix #[confik(default = ...)] with from / try_from: when no data is merged, the default expression is evaluated as the target field type (after the macro’s Into::into), matching the struct_default missing-data path, instead of being forced to unify with the intermediate builder type.
  • Note although this was likely what your code was assuming (and was only working due to the implied Into), this may break existing code.

confik: v0.15.8

• No significant changes since 0.15.7.

confik: v0.15.7

• No significant changes since 0.15.6.

confik: v0.15.6

• Implement Configuration for jiff types under the jiff-0_2 feature flag:
  • Timestamp, Zoned, SignedDuration, Span
  • civil::Date, civil::Time, civil::DateTime
• Add serde(with = ...) modules under confik::jiff for Option<T> fields requiring non-default serialization formats:
  • confik::jiff::timestamp::{second, millisecond, microsecond, nanosecond}::optional — integer epoch timestamps
  • confik::jiff::duration::friendly::compact::optional — friendly compact format for Option<SignedDuration>
  • confik::jiff::span::friendly::compact::optional — friendly compact format for Option<Span>
  • confik::jiff::unsigned_duration::optional and confik::jiff::unsigned_duration::friendly::compact::optional — ISO 8601 and friendly compact format for Option<std::time::Duration>

confik: v0.15.5

• Add RON source support behind new crate feature ron-0_12 (off-by-default).
• Add YAML source support behind new crate feature yaml_serde-0_10 (off-by-default).

confik: v0.15.4

• Add serde(with = ...) module confik::humantime under the humantime feature flag, for humantime support via serde_humantime for the builder of Option<Duration>. E.g.

  #[derive(Debug, PartialEq, Eq, Configuration)]
  struct Config {
      #[confik(forward(serde(with = "confik::humantime::option")))]
      timeout: Option<Duration>,
  }

confik: v0.15.3

• Implement Configuration for serde_json::Value
  • This is a very simple way to implement try_from, see the foreign_type_via_value for an example.

confik: v0.15.2

• Add hot-reloadable configuration support with ReloadableConfig trait and ReloadingConfig wrapper. Requires the reloading feature (depends on arc-swap).
  • ReloadableConfig trait defines how to build a configuration instance.
  • ReloadingConfig<T, F> provides lock-free atomic configuration swapping.
  • Optional callbacks via with_on_update() for reload notifications.
  • Optional SIGHUP signal handler via spawn_signal_handler() (requires signal feature, depends on signal-hook).
  • Optional tracing support for logging reload errors (requires tracing feature).
• Update toml dependency to 1. This means config files now support the TOML v1.1 spec with some new features.
• Fix try_from failure error, path now includes the (previously missing) failed field's name.
• Minimum supported Rust version (MSRV) is now 1.81.
