Expand description

The type of a configuration error.



The configuration file was not found.


There was an I/O error while reading the configuration file.

Io(Error, &'static str)

There was an I/O error while setting a configuration parameter.

Parameters: (io_error, config_param_name)

BadFilePath(PathBuf, &'static str)

The path at which the configuration file was found was invalid.

Parameters: (path, reason)


An environment specified in ROCKET_ENV is invalid.

Parameters: (environment_name)


An environment specified as a table [environment] is invalid.

Parameters: (environment_name, filename)

BadType(String, &'static str, &'static strOption<PathBuf>)

A config key was specified with a value of the wrong type.

Parameters: (entry_name, expected_type, actual_type, filename)

ParseError(StringPathBufStringOption<(usize, usize)>)

There was a TOML parsing error.

Parameters: (toml_source_string, filename, error_description, line/col)


There was a TOML parsing error in a config environment variable.

Parameters: (env_key, env_value, error)


The entry (key) is unknown.

Parameters: (key)


The entry (key) was expected but was missing.

Parameters: (key)
