Enum adventjson::JsonError

pub enum JsonError {
    Empty,
    InvalidChar(char, usize),
    UnterminatedString,
    EndedOnEscape,
    UnknownEscapeSequence(char),
    NonStringAsKey,
    InvalidCodepoint,
    InvalidNumber,
}

An error that occured while parsing a json file

The reading functions work recursive, that means major errors might end up in the wrong category, for example mismatched parantheses result in an Empty error:

 assert_eq!(JsonObject::read("[[[]]"), Err(Empty));

Variants

Empty

The input was empty (or only whitespace)

InvalidChar(char, usize)

At the given position the given character was read invalidly

UnterminatedString

A string with no closing quote

EndedOnEscape

The input ended on a backslash

UnknownEscapeSequence(char)

An unknown escape sequence was encountered

NonStringAsKey

A not string was used as key in an JsonObject::Obj

InvalidCodepoint

Per ‘\uXXXX’ was an invalid code point specified

InvalidNumber

A number that is invalid in json, but is a perfectly fine floating-point number.

Trait Implementations

impl Clone for JsonError

fn clone(&self) -> JsonError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JsonError

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

Formats the value using the given formatter.

impl Display for JsonError

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for JsonError

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.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl Hash for JsonError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<JsonError> for JsonError

fn eq(&self, other: &JsonError) -> bool

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

fn ne(&self, other: &JsonError) -> bool

This method tests for !=.
