Struct serde_qs::Error

pub struct Error(pub ErrorKind, _);

The Error type.

This tuple struct is made of two elements:

• an ErrorKind which is used to determine the type of the error.
• An internal State, not meant for direct use outside of error_chain internals, containing:
  • a backtrace, generated when the error is created.
  • an error chain, used for the implementation of Error::cause().

Methods

impl Error

fn from_kind(kind: ErrorKind) -> Error

Constructs an error from a kind, and generates a backtrace.

fn with_chain<E, K>(error: E, kind: K) -> Error where
    E: Error + Send + 'static,
    K: Into<ErrorKind>, 

Constructs a chained error from another error and a kind, and generates a backtrace.

fn with_boxed_chain<K>(error: Box<Error + Send>, kind: K) -> Error where
    K: Into<ErrorKind>, 

Construct a chained error from another boxed error and a kind, and generates a backtrace

fn kind(&self) -> &ErrorKind

Returns the kind of the error.

fn iter(&self) -> Iter

Iterates over the error chain.

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

Returns the backtrace associated with this error.

fn chain_err<F, EK>(self, error: F) -> Error where
    F: FnOnce() -> EK,
    EK: Into<ErrorKind>, 

Extends the error chain with a new entry.

impl Error

fn top_level(object: &'static str) -> Error

Generate error to show top-level type cannot be deserialized.
