The Error trait allows Deserialize implementations to create descriptive error messages belonging to the Deserializer against which they are currently running.

Every Deserializer declares an Error type that encompasses both general-purpose deserialization errors as well as errors specific to the particular deserialization format.

Most deserializers should only need to provide the Error::custom method and inherit the default behavior for the other methods.

Required Methods

fn custom(msg: impl Display) -> Self

Raised when there is general error when deserializing a type.

Provided Methods

fn invalid_product_length<'de, T>(len: usize, expected: &T) -> Selfwhere T: ProductVisitor<'de>,

The product length was not as promised.

fn missing_field<'de, T>( index: usize, field_name: Option<&str>, prod: &T ) -> Selfwhere T: ProductVisitor<'de>,

There was a missing field at index.

fn duplicate_field<'de, T>( index: usize, field_name: Option<&str>, prod: &T ) -> Selfwhere T: ProductVisitor<'de>,

A field with index was specified more than once.

fn unknown_field_name<'de, T>(field_name: &str, expected: &T) -> Selfwhere T: FieldNameVisitor<'de>,

A field with name field_name does not exist.

fn unknown_variant_tag<'de, T>(tag: u8, expected: &T) -> Selfwhere T: SumVisitor<'de>,

The tag does not specify a variant of the sum type.

fn unknown_variant_name<T>(name: &str, expected: &T) -> Selfwhere T: VariantVisitor,

The name is not that of a variant of the sum type.

Object Safety

This trait is not object safe.
