Expand description

Represents all possible errors that can occur when working with configuration.

Variants

Frozen

Configuration is frozen and no further mutations can be made.

NotFound(String)

Configuration property was not found

PathParse(ErrorKind)

Configuration path could not be parsed.

FileParse

Configuration could not be parsed from file.

Show fields

Fields of FileParse

uri: Option<String>

The URI used to access the file (if not loaded from a string). Example: /path/to/config.json

cause: Box<dyn Error + 'static + Sync + Send, Global>

The captured error from attempting to parse the file in its desired format. This is the actual error object from the library used for the parsing.

Type

Value could not be converted into the requested type.

Show fields

Fields of Type

origin: Option<String>

The URI that references the source that the value came from. Example: /path/to/config.json or Environment or etcd://localhost

unexpected: Unexpected

What we found when parsing the value

expected: &'static str

What was expected when parsing the value

key: Option<String>

The key in the configuration hash of this value (if available where the error is generated).

Message(String)

Custom message

Foreign(Box<dyn Error + 'static + Sync + Send, Global>)

Unadorned error from a foreign origin.
