}

A configuration error.

Variants

EmptyPrefix

Environment variable prefix was empty.

MissingField

Requested field was missing from the configuration.

Fields

help_text: String

Help text describing how to set the missing field.

This is meant to be displayed to the user, and includes environment variable-specific text if environment variables had been loaded originally.

field: Cow<'static, str>

Name of the missing field.

InvalidFieldType

Requested field’s data type was not the unexpected data type.

Fields

field: String

Name of the invalid field.

This is a period-separated path to the field.

expected_ty: String

Expected data type.

actual_ty: String

Actual data type.

Generic

Generic configuration error.

Fields

source: GenericError

Error source.

Secrets

Secrets resolution error.

Fields

source: Error

Trait Implementations

impl Debug for ConfigurationError

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

Formats the value using the given formatter.

impl Display for ConfigurationError

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

Formats the value using the given formatter.

impl Error for ConfigurationError

where Self: Debug + Display,

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

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

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 ErrorCompat for ConfigurationError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl From<Error> for ConfigurationError

fn from(e: Error) -> Self

Converts to this type from the input type.
