Error is a trait that allows a Deserialize to generically create a Deserializer error.

Required Methods

fn syntax(msg: &str) -> Self

Raised when there is general error when deserializing a type.

fn end_of_stream() -> Self

Raised when a Deserialize type unexpectedly hit the end of the stream.

fn unknown_field(field: &str) -> Self

Raised when a Deserialize struct type received an unexpected struct field.

fn missing_field(field: &'static str) -> Self

Raised when a Deserialize struct type did not receive a field.

Provided Methods

fn length_mismatch(_len: usize) -> Self

Raised when a fixed sized sequence or map was passed in the wrong amount of arguments.

fn type_mismatch(_type: Type) -> Self

Raised when a Deserialize was passed an incorrect type.

fn invalid_value(msg: &str) -> Self

Raised when a Deserialize was passed an incorrect value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
