Enum config::ConfigError
[−]
[src]
pub enum ConfigError { Frozen, NotFound(String), PathParse(ErrorKind), FileParse { uri: Option<String>, cause: Box<Error + Send + Sync>, }, Type { origin: Option<String>, unexpected: Unexpected, expected: &'static str, key: Option<String>, }, Message(String), Foreign(Box<Error + Send + Sync>), }
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.
Fields of FileParse
uri: Option<String> | The URI used to access the file (if not loaded from a string).
Example: |
cause: Box<Error + Send + Sync> | 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.
Fields of Type
origin: Option<String> | The URI that references the source that the value came from.
Example: |
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<Error + Send + Sync>)
Unadorned error from a foreign origin.
