pub struct AsyncConfigBuilder {}
Expand description

The asynchronous configuration builder.

Similar to a ConfigBuilder it maintains a set of defaults, a set of sources, and overrides.

Defaults do not override anything, sources override defaults, and overrides override anything else. Within those three groups order of adding them at call site matters - entities added later take precedence.

For more detailed description and examples see ConfigBuilder. AsyncConfigBuilder is just an extension of it that takes async functions into account.

To obtain a Config call build or build_cloned

Example

Since this library does not implement any AsyncSource an example in rustdocs cannot be given. Detailed explanation about why such a source is not implemented is in AsyncSource’s documentation.

Refer to ConfigBuilder for similar API sample usage or to the examples folder of the crate, where such a source is implemented.
