Detailed Description

Represents a permission bitmask (refer to enum dpp::permissions) which are held in an uint64_t.

Constructor & Destructor Documentation

permission() [1/2]

constexpr dpp::permission::permission ( )

constexprdefault

Default constructor, initializes permission to 0.

permission() [2/2]

constexpr dpp::permission::permission ( uint64_t  value )

inlineconstexprnoexcept

Bitmask constructor, initializes permission to the argument.

Parameters

value

The bitmask to initialize the permission to

Member Function Documentation

add()

template<typename... T>

constexpr std::enable_if_t<(std::is_convertible_v<T, uint64_t> && ...), permission&> dpp::permission::add ( T...  values )

inlineconstexprnoexcept

Add a permission with the Bitwise OR operation.

Template Parameters

T	one or more uint64_t permission bits

Parameters

values

The permissions (from dpp::permissions) to add

Example:

permission.add(dpp::p_view_channel, dpp::p_send_messages);
// Adds p_view_channel and p_send_messages to the permission bitmask

Returns

permission& reference to self for chaining

can()

template<typename... T>

constexpr bool dpp::permission::can ( T...  values ) const

inlineconstexprnoexcept

Check for certain permissions, taking into account administrator privileges. It uses the Bitwise AND operator.

Template Parameters

T	one or more uint64_t permission bits

Parameters

values

The permissions (from dpp::permissions) to check for

Example:

bool is_mod = permission.can(dpp::p_kick_members, dpp::p_ban_members);
// Returns true if it has permission to p_kick_members and p_ban_members

Returns

bool True if it has all the given permissions or dpp::p_administrator

can_any()

template<typename... T>

constexpr bool dpp::permission::can_any ( T...  values ) const

inlineconstexprnoexcept

Check for certain permissions, taking into account administrator privileges. It uses the Bitwise AND operator.

Template Parameters

T	one or more uint64_t permission bits

Parameters

values

The permissions (from dpp::permissions) to check for

Example:

bool is_mod = permission.can_any(dpp::p_kick_members, dpp::p_ban_members);
// Returns true if it has permission to p_kick_members or p_ban_members

Returns

bool True if it has any of the given permissions or dpp::p_administrator

has()

template<typename... T>

constexpr bool dpp::permission::has ( T...  values ) const

inlineconstexprnoexcept

Check for permission flags set. It uses the Bitwise AND operator.

Template Parameters

T	one or more uint64_t permission bits

Parameters

values

The permissions (from dpp::permissions) to check for

Example:

bool is_mod = permission.has(dpp::p_kick_members, dpp::p_ban_members);
// Returns true if the permission bitmask contains p_kick_members and p_ban_members

Returns

bool True if it has all the given permissions

has_any()

template<typename... T>

constexpr bool dpp::permission::has_any ( T...  values ) const

inlineconstexprnoexcept

Check for permission flags set. It uses the Bitwise AND operator.

Template Parameters

T	one or more uint64_t permission bits

Parameters

values

The permissions (from dpp::permissions) to check for

Example:

bool is_mod = permission.has_any(dpp::p_administrator, dpp::p_ban_members);
// Returns true if the permission bitmask contains p_administrator or p_ban_members

Returns

bool True if it has any of the given permissions

operator uint64_t()

constexpr dpp::permission::operator uint64_t ( ) const

inlineconstexprnoexcept

For acting like an integer.

Returns

The permission bitmask value

operator uint64_t &()

constexpr dpp::permission::operator uint64_t & ( )

inlineconstexprnoexcept

For acting like an integer.

Returns

A reference to the permission bitmask value

remove()

template<typename... T>

constexpr std::enable_if_t<(std::is_convertible_v<T, uint64_t> && ...), permission&> dpp::permission::remove ( T...  values )

inlineconstexprnoexcept

Remove a permission with the Bitwise NOT operation.

Template Parameters

T	one or more uint64_t permission bits

Parameters

values

The permissions (from dpp::permissions) to remove

Example:

permission.remove(dpp::p_view_channel, dpp::p_send_messages);
// Removes p_view_channel and p_send_messages permission

Returns

permission& reference to self for chaining

set()

template<typename... T>

constexpr std::enable_if_t<(std::is_convertible_v<T, uint64_t> && ...), permission&> dpp::permission::set ( T...  values )

inlineconstexprnoexcept

Assign permissions. This will reset the bitmask to the new value.

Template Parameters

T	one or more uint64_t permission bits

Parameters

values

The permissions (from dpp::permissions) to set

Example:

permission.set(dpp::p_view_channel, dpp::p_send_messages);

Returns

permission& reference to self for chaining
