View Source Nostrum.Permission (Nostrum v0.6.0)

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
