smats::DelegatingHasher Struct Reference

#include <hash.hpp>

Public Types
using	Func = std::function<void(const void*, size_t)>
using	result_type = typename DefaultHashAlgorithm::result_type
	Necessary to be accepted by hash_append.

Public Member Functions
	DelegatingHasher (Func func)
void	operator() (const void *data, size_t length) noexcept
	operator result_type () noexcept

Private Attributes
const Func	func_
	Concrete hash algorithm implementation.

Detailed Description

A simple struct that wraps a specific hash algorithm into a std::function. It is useful for passing a concrete HashAlgorithm implementation through into non-templated code.

Constructor & Destructor Documentation

DelegatingHasher()

smats::DelegatingHasher::DelegatingHasher ( Func func )

inlineexplicit

Construct a new DelegatingHasher object.

Precondition

The function must be non-empty.

Parameters

func	hash algorithm implementation

Member Function Documentation

operator result_type()

smats::DelegatingHasher::operator result_type ( )

inlinenoexcept

Placeholder for the return type.

It is necessary for this struct to correctly implement the Hashable concept.

Warning

This function should never be called.

operator()()

void smats::DelegatingHasher::operator() ( const void * data, size_t length )

inlinenoexcept

Delegation of the hash algorithm to func_ .

Parameters

data	data to hash
length	length of the data
