--- Returns the critical roles for a guild
---
--- The \`\`set_member_roles\`\` here are the pre-defined roles set by the server that should be locked down
--- If \`\`set_member_roles\`\` is empty (no overrides), the @everyone role is returned
function getCriticalRoles(guild: discord.GuildObject, set_member_roles: {discord.Snowflake}) -> set.Set<discord.Snowflake> end

--- Merges a set of lockdown sharable data's assuming that least recent lockdowns are first
function mergelsd(lsd: {handle.LockdownSharableData}) -> handle.LockdownSharableData end

--- Returns the underlying permissions (or otherwise) for a given state
---
--- This works by merging the shareable data from all lockdowns in the order of least recent first,
--- to ensure that the permissions are derived from the least recent lockdowns first and then using
--- \`f\` to extract the desired data from the merged sharable data
function getunderlying<T, U>(lockdowns: {mode.Lockdown}, state: T, f: (handle.LockdownSharableData, T) -> U?) -> U? end

f: (handle.LockdownSharableData, T) -> U?

--- Returns the underlying role permissions if any
function getunderlyingrolepermissions(lockdowns: {mode.Lockdown}, role_id: discord.Snowflake) -> string? end

--- Returns the underlying channel permission overwrites if any
function getunderlyingchannelpermissions(lockdowns: {mode.Lockdown}, channel_id: discord.Snowflake) -> {discord.OverwriteObject}? end

--- Replaces a role in the guild roles list
function replacerole(data: mode.BaseLockdownModeData, role: discord.GuildRoleObject, hint_idx: number?) end

--- Replaces a channel in the guild channel list
function replacechannel(data: mode.BaseLockdownModeData, channel: discord.ChannelObject, hint_idx: number?) end
