The type of a configuration error.

Variants

BadCWD

The current working directory could not be determined.

NotFound

The configuration file was not found.

IoError

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)

BadEnv(String)

An environment specified in ROCKET_ENV is invalid.

Parameters: (environment_name)

BadEntry(String, PathBuf)

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

Parameters: (environment_name, filename)

BadType(String, &'static str, &'static str, PathBuf)

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

Parameters: (entry_name, expected_type, actual_type, filename)

ParseError(String, PathBuf, String, Option<(usize, usize)>)

There was a TOML parsing error.

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

BadEnvVal(String, String, String)

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

Parameters: (env_key, env_value, error)

UnknownKey(String)

The entry (key) is unknown.

Parameters: (key)

Methods

`impl ConfigError`
[src]

`pub fn pretty_print(&self)`
[src]

Prints this configuration error with Rocket formatting.

`pub fn is_not_found(&self) -> bool`
[src]

Returns true if self is of NotFound variant.

Example

use rocket::config::ConfigError;

let error = ConfigError::NotFound;
assert!(error.is_not_found());
