Variants

NonDirExpr

A Dir expression was not an Expr::Map.

NonTableExpr

A table expression was not an Expr::Map.

NonTableConfig

A Dir entry for lib did not contain a table value.

Fields

lib: Symbol

The library whose Dir entry was malformed.

UnsupportedDirKey

A Dir key could not be interpreted as a library id.

Fields

key: Expr

The unsupported key expression.

InvalidLibId

A library id or id segment is not safe for config use.

Fields

id: String

The rejected id.

InvalidPathSegment

A library config path segment was rejected.

Fields

segment: String

The rejected segment.

MissingField

A required field was absent from a config table.

Fields

key: String

The missing field name.

TypeMismatch

A config field had a different shape than the caller requested.

Fields

key: String

The field name.

expected: &'static str

The expected shape.

Trait Implementations

impl Clone for ConfigError

fn clone(&self) -> ConfigError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ConfigError

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<SymbolError> for ConfigError

fn from(error: SymbolError) -> Self

Converts to this type from the input type.

impl PartialEq for ConfigError

fn eq(&self, other: &ConfigError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
