Specific kinds of validation errors produced when RON data does not match a schema.

Variants

MissingField

A required field defined in the schema is absent from the data.

Fields

field_name: String

The name of the missing field.

UnknownField

The data contains a field not defined in the schema.

Fields

field_name: String

The name of the unrecognized field.

TypeMismatch

A value exists but has the wrong type.

Fields

expected: String

The type expected by the schema.

found: String

A description of what was actually found.

InvalidEnumVariant

A bare identifier does not match any variant of the expected enum.

Fields

enum_name: String

The enum the identifier was validated against.

variant: String

The identifier that was found.

valid: Vec<String>

All valid variants for this enum.

InvalidOptionValue

The value inside Some(...) has the wrong type.

Fields

expected: String

The type expected by the schema.

found: String

A description of what was actually found.

InvalidListElement

A list element has the wrong type.

Fields

index: usize

The 0-based index of the offending element.

expected: String

The type expected by the schema.

found: String

A description of what was actually found.

ExpectedStruct

Expected a struct (...) but found a non-struct value.

Fields

found: String

A description of what was actually found.

ExpectedList

Expected a list [...] but found a non-list value.

Fields

found: String

A description of what was actually found.

ExpectedOption

Expected Some(...) or None but found something else.

Fields

found: String

A description of what was actually found.

ExpectedMap

Expected a map { ... } but found a non-map value.

Fields

found: String

A description of what was actually found.

InvalidMapKey

A map key has the wrong type.

Fields

key: String

A string representation of the key.

expected: String

The type expected by the schema.

found: String

A description of what was actually found.

InvalidMapValue

A map value has the wrong type.

Fields

key: String

A string representation of the key this value belongs to.

expected: String

The type expected by the schema.

found: String

A description of what was actually found.

InvalidVariantData

An enum variant’s associated data does not match the expected type.

Fields

enum_name: String

The enum name.

variant: String

The variant name.

expected: String

The type expected by the schema.

found: String

A description of what was actually found.

ExpectedTuple

Expected a tuple (...) but found a non-tuple value.

Fields

found: String

A description of what was actually found.

TupleLengthMismatch

A tuple has the wrong number of elements.

Fields

expected: usize

The number of elements expected by the schema.

found: usize

The number of elements found in the data.

InvalidTupleElement

A tuple element has the wrong type.

Fields

index: usize

The 0-based index of the offending element.

expected: String

The type expected by the schema.

found: String

A description of what was actually found.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl PartialEq for ErrorKind

fn eq(&self, other: &ErrorKind) -> 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.
