[−][src]Struct embedded_error_chain::Error

#[repr(transparent)]pub struct Error<C>(_, _);

An error that consists of an ErrorCode that belongs to an ErrorCategory and optionally up to 4 chained error codes of different types that implement ErrorCategory.

Implementations

impl<C> Error<C>[src]

pub const fn new_raw(error_code: ErrorCode) -> Error<C>[src]

Create a new Error with an empty chain from the supplied raw error_code.

impl<C> Error<C>[src]

pub const fn chain_capacity(&self) -> usize[src]

Get the capacity of the error chain.

Always returns ERROR_CHAIN_LEN.

impl<C: ErrorCategory> Error<C>[src]

pub fn new(error_code: C) -> Error<C>[src]

Create a new Error with an empty chain from the supplied error_code.

pub fn code(&self) -> C[src]

Get the error code of the latest error.

pub fn chain_len(&self) -> usize[src]

Get the length of the error chain.

pub fn caused_by<T: ErrorCategory>(&self, error_code: T) -> bool[src]

Query if this error was caused by error_code which belongs to the error category T.

pub fn code_of_category<T: ErrorCategory>(&self) -> Option<T>[src]

Query the error code contained in this error that belongs to the ErrorCategory T. Return None if this error was not caused by the specified error category.

pub fn iter(&self) -> ErrorIterⓘ

Notable traits for ErrorIter

impl Iterator for ErrorIter type Item = (ErrorCode, ErrorCategoryHandle);
[src]

Create an iterator that iterates over all error codes in this error.
