Struct clams::config::ConfigError

pub struct ConfigError(pub ConfigErrorKind, _);

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 ConfigError

pub fn from_kind(kind: ConfigErrorKind) -> ConfigError

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

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

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

pub fn with_boxed_chain<K>(error: Box<dyn Error + Send>, kind: K) -> ConfigError where
    K: Into<ConfigErrorKind>, 

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

pub fn kind(&self) -> &ConfigErrorKind

Returns the kind of the error.

pub fn iter(&self) -> Iter

Iterates over the error chain.

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

Returns the backtrace associated with this error.

pub fn chain_err<F, EK>(self, error: F) -> ConfigError where
    F: FnOnce() -> EK,
    EK: Into<ConfigErrorKind>, 

Extends the error chain with a new entry.

pub fn description(&self) -> &str

A short description of the error. This method is identical to Error::description()
