Function Documentation

combineHash()

size_t Nickvision::Helpers::CodeHelpers::combineHash ( size_t a, size_t b )

noexcept

Combines two hash values together.

Parameters

a	The first hash value
b	The second hash value

Returns

The combined hash value

convertUrlMapToVector()

std::vector< std::string > Nickvision::Helpers::CodeHelpers::convertUrlMapToVector ( const std::unordered_map< std::string, std::string > & urls )

noexcept

Converts a map of URLs to a vector.

Parameters

urls	The map of URLs

Returns

The vector of URLs

getLastSystemError()

std::string Nickvision::Helpers::CodeHelpers::getLastSystemError ( )

noexcept

Get the last system api call error message.

Returns

The last system error message

readFileBytes()

std::vector< std::byte > Nickvision::Helpers::CodeHelpers::readFileBytes ( const std::filesystem::path & path )

noexcept

Reads a file as a vector of bytes.

Parameters

path	The path to the file

Returns

The bytes from the file

unmove()

template<typename T>

const T & Nickvision::Helpers::CodeHelpers::unmove ( T && t )

noexcept

Unmoves a value.

Parameters

t	An rvalue of T

Returns

The lvalue of t

writeFileBytes()

bool Nickvision::Helpers::CodeHelpers::writeFileBytes ( const std::filesystem::path & path, const std::vector< std::byte > & bytes, bool overwrite = true )

noexcept

Writes a vector of bytes to a file.

Parameters

path	The path to the file
bytes	The bytes to write
overwrite	Whether or not to overwrite the file if it already exists

Returns

True if successful, false otherwise. False is returned if overwrite is false and the file exists.
