Variants

MissingRequiredField

A required field is missing from the configuration.

Fields

field_path: String

The path to the missing field (e.g., “proxy.id” or “network.default.bind_address”).

InvalidType

A field has an invalid type.

Fields

field_path: String

The path to the field with the wrong type.

expected: String

The expected type according to the schema.

found: String

The actual type found in the TOML.

InvalidEnumValue

A field value is not one of the allowed enum values.

Fields

field_path: String

The path to the field with the invalid value.

value: String

The value that was found.

allowed: Vec<String>

The list of allowed values.

OutOfRange

A numeric value is outside the allowed range.

Fields

field_path: String

The path to the field that is out of range.

value: String

The value that was found.

min: Option<String>

The minimum allowed value, if specified.

max: Option<String>

The maximum allowed value, if specified.

InvalidArrayLength

An array has an invalid number of items.

Fields

field_path: String

The path to the array field.

length: usize

The actual length of the array.

min: Option<usize>

PatternMismatch

A field value does not match the required pattern.

Fields

field_path: String

The path to the field with the pattern mismatch.

pattern: String

The pattern that should have been matched.

ConditionalRequirementFailed

A conditionally required field is missing.

Fields

field_path: String

The path to the missing field.

condition: String

The condition that triggered the requirement.

SchemaParseError(String)

Failed to parse the schema TOML.

TomlParseError(String)

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

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<ValidationError> for RunbeamError

fn from(err: ValidationError) -> Self

Converts to this type from the input type.
