Errors that can occur when loading configuration

Variants

IoError

Failed to read the configuration file

Fields

source: Error

path: String

ParseError(String)

Failed to parse the configuration content (TOML or JSON)

FileExists

Configuration file already exists

Fields

path: String

CircularExtends

Circular extends reference detected

Fields

path: String

chain: Vec<String>

ExtendsDepthExceeded

Extends chain exceeds maximum depth

Fields

path: String

max_depth: usize

ExtendsNotFound

Extends target file not found

Fields

path: String

from: String

ExtendsUndefinedVar

An extends path referenced an environment variable that is not set

Fields

var: String

The variable as the message may name it: $NAME, or WITHHELD when the file that wrote it was itself reached through extends and its text may not be repeated (see [ConfigOrigin]).

Trait Implementations

impl Debug for ConfigError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ConfigError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ConfigError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<DiscoveredConfigError> for ConfigError

fn from(error: DiscoveredConfigError) -> Self

Converts to this type from the input type.
