Combine combines the passed errors into a single error. If zero arguments were passed or if all items are nil, a nil error is returned. Combine(nil

Append appends the given errors together. Either value may be nil. This function is a specialization of Combine for the common case where there are o

Is attempts to match the provided error against errors in the error list. This function allows errors.Is to traverse the values stored on the multier

AppendInto appends an error into the destination of an error pointer and returns whether the error being appended was non-nil. var err error multie

Close builds an Invoker that closes the provided io.Closer. Use it with AppendInvoke to close io.Closers and append their results into an error. For

Versions of Go before 1.20 did not support the Unwrap() []error method. This provides a similar behavior by implementing the Is(..) and As(..) methods

Errors returns a slice containing zero or more errors that the supplied error is composed of. If the error is nil, a nil slice is returned. err := m

AppendInvoke appends the result of calling the given Invoker into the provided error pointer. Use it with named returns to safely defer invocation of

Every compares every error in the given err against the given target error using [errors.Is], and returns true only if every comparison returned true.

Errors returns the list of underlying errors. This slice MUST NOT be modified.

fromSlice converts the given list of errors into a single error.

AppendFunc is a shorthand for [AppendInvoke]. It allows using function or method value directly without having to wrap it into an [Invoker] interface.

Inspects the given slice of errors so that we can efficiently allocate space for it.

Writes s to the writer with the given prefix added before each line after the first.

Invoke calls the supplied function and returns its result.

Unwrap returns a list of errors wrapped by this multierr.
