View Source Nostrum.Permission (Nostrum v0.10.0)

Functions that work on permissions.

Some functions return a list of permissions. You can use enumerable functions to work with permissions:

alias Nostrum.Cache.GuildCache
alias Nostrum.Struct.Guild.Member

guild = GuildCache.get!(279093381723062272)
member = Map.get(guild.members, 177888205536886784)
member_perms = Member.guild_permissions(member, guild)

if :administrator in member_perms do
  IO.puts("This user has the administrator permission.")
end

:change_nickname

iex> Nostrum.Permission.from_bit!(0)
** (ArgumentError) expected a valid bit, got: `0`

from_bitset(bitset)

@spec from_bitset(bitset()) :: [t()]

Converts the given bitset to a list of permissions.

If invalid bits are given they will be omitted from the results.

Examples

iex> Nostrum.Permission.from_bitset(0x08000002)
[:manage_nicknames, :kick_members]

iex> Nostrum.Permission.from_bitset(0x4000000000000)

8

to_bitset(permissions)

@spec to_bitset(Enum.t()) :: bitset()
