Errors raised while traversing a parsed configuration value.

Variants

InvalidPath

The requested path string is malformed.

Fields

path: String

The malformed config path.

MissingKey

The requested key was missing.

Fields

path: String

The full missing config path.

MissingIndex

The requested array element was missing.

Fields

path: String

The full missing config path.

InvalidKeyAccess

A key access was attempted on a non-table value.

Fields

path: String

The full config path that was being traversed.

key: String

The key fragment whose access failed.

value_type: &'static str

The type of the parent value that rejected the key access.

InvalidIndexAccess

An index access was attempted on a non-array value.

Fields

path: String

The full config path that was being traversed.

index: usize

The index fragment whose access failed.

value_type: &'static str

The type of the parent value that rejected the index access.

Implementations

impl ConfigPathError

pub fn is_missing(&self) -> bool

Returns true if the error denotes a missing path element.

Trait Implementations

impl Clone for ConfigPathError

fn clone(&self) -> ConfigPathError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigPathError

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

Formats the value using the given formatter.

impl Display for ConfigPathError

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

Formats the value using the given formatter.

impl Error for ConfigPathError

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<ConfigPathError> for ConfigError

fn from(error: ConfigPathError) -> ConfigError

Converts to this type from the input type.

impl PartialEq for ConfigPathError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
