This type represents all possible errors that can occur when deserializing libtcod config files.

Variants

Serde

An error reported to us by serde itself.

Fields of Serde

msg: String

The message serde provided.

UnexpectedToken

A token that was unexpected was encountered.

Fields of UnexpectedToken

value: String

The value of the unexpected token.

token_type: String

The type of token we (thought we) found

range: Range<usize>

The location in the source string where the token was encountered.

expected: &'static str

The token/value the deserializer was expecting at this location.

UnexpectedStruct

A different struct than was expected was encountered.

Fields of UnexpectedStruct

name: String

The name of the encountered struct.

expected: String

The expected name of the struct.

MissingInstanceName

All structs must have an instance_name field. This field is used to hold the value within libtcod_struct_name "libtcod_instance_name" { ... }. Structs without an instance name will have their value set to "".

InvalidChar

An invalid char representation was encountered.

Fields of InvalidChar

source: InvalidCharError

The cause of the invalid char.

MultiLineStringOnBorrowedStr

This format supports multi-line strings, but they are not necessarily contiguous, so if such an non-contiguous variant is encountered on a string slice field, this error is returned.

Fields of MultiLineStringOnBorrowedStr

value: String

The value of the token where this error was triggered.

range: Range<usize>

The location in the source string where the token was encountered.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error where
    Self: Debug + Display, 

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

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

fn backtrace(&self) -> Option<&Backtrace>

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

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

impl Error for Error

fn custom<T>(msg: T) -> Self where
    T: Display, 

Raised when there is general error when deserializing a type.

fn invalid_type(unexp: Unexpected, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a type different from what it was expecting.

fn invalid_value(unexp: Unexpected, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

fn invalid_length(len: usize, exp: &dyn Expected) -> Self

Raised when deserializing a sequence or map and the input data contains too many or too few elements.

fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize enum type received a variant with an unrecognized name.

fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize struct type received a field with an unrecognized name.

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

Raised when a Deserialize struct type expected to receive a required field with a particular name but that field was not present in the input.

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

Raised when a Deserialize struct type received more than one of the same field.

impl ErrorCompat for Error

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.
