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, Option<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)
Missing(String)
The entry (key) was expected but was missing.
Parameters: (key)
Methods

[src]
Returns true
if self
is of NotFound
variant.
Example
use rocket::config::ConfigError; let error = ConfigError::NotFound; assert!(error.is_not_found());
