Errors that can occur when serializing a type.

Variants

UnsupportedType

Indicates that a Rust type was requested to be serialized but it was not supported.

Currently the TOML format does not support serializing types such as enums, tuples and tuple structs.

KeyNotString

The key of all TOML maps must be strings, but serialization was attempted where the key of a map was not a string.

KeyNewline

Keys in maps are not allowed to have newlines.

ArrayMixedType

Arrays in TOML must have a homogenous type, but a heterogeneous array was emitted.

ValueAfterTable

All values in a TOML table must be emitted before further tables are emitted. If a value is emitted after a table then this error is generated.

DateInvalid

A serialized date was invalid.

UnsupportedNone

None was attempted to be serialized, but it's not supported.

Custom(String)

A custom error which could be generated when serializing a particular type.

Trait Implementations

impl Debug for Error

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq for Error

fn eq(&self, __arg_0: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Error) -> bool

This method tests for !=.

impl Eq for Error

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn description(&self) -> &str

A short description of the error.

fn cause(&self) -> Option<&Error>

The lower-level cause of this error, if any.

impl Error for Error

fn custom<T: Display>(msg: T) -> Error

Raised when a Serialize implementation encounters a general error while serializing a type.
