Enum ErrorKind 

#[non_exhaustive]
pub enum ErrorKind {
    NotEnoughElements(usize),
    TooManyElements(usize),
    ListNotAllowed,
    SymbolNotAllowed,
    StringParsing(&'static str),
    UnknownField(Box<str>),
    InvalidElement,
}

The kind of error that occurred during token parsing.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotEnoughElements(usize)

The sublist contains fewer elements than the given minimum.

TooManyElements(usize)

The sublist contains more elements than expected by a specified amount.

ListNotAllowed

No list is allowed in this context.

SymbolNotAllowed

No symbol is allowed in this context.

StringParsing(&'static str)

String parsing failed for the named type.

UnknownField(Box<str>)

The named field does not exist.

InvalidElement

Some specific element is invalid.

Trait Implementations

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl Error for ErrorKind

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

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<ErrorKind> for Error

fn from(kind: ErrorKind) -> Self

Converts to this type from the input type.
