Errors that can occur when serializing a type.

Variants

UnsupportedType

[−] Expand description

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

[−] Expand description

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

ValueAfterTable

[−] Expand description

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

[−] Expand description

A serialized date was invalid.

NumberInvalid

[−] Expand description

A serialized number was invalid.

UnsupportedNone

[−] Expand description

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

Custom(String)

[−] Expand description

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

Trait Implementations

impl Clone for Error[+]

[+] Show hidden undocumented items

fn clone(&self) -> Error[−]

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

impl Debug for Error[+]

[+] Show hidden undocumented items

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

Formats the value using the given formatter.

impl Display for Error[+]

[+] Show hidden undocumented items

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error[+]

[+] Show hidden undocumented items

pub fn source(&self) -> Option<&(dyn Error + 'static)>[−]

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

pub fn backtrace(&self) -> Option<&Backtrace>[−]

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str[−]

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl Error for Error[+]

[+] Show hidden undocumented items

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

Used when a Serialize implementation encounters any error while serializing a type.

impl PartialEq<Error> for Error[+]

[+] Show hidden undocumented items

fn eq(&self, other: &Error) -> bool[−]

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

fn ne(&self, other: &Error) -> bool[−]

This method tests for !=.
