Struct InMemoryCachePermissions

pub struct InMemoryCachePermissions<'a, CacheModels: CacheableModels> { /* private fields */ }

Available on crate feature permission-calculator only.

Calculate the permissions of a member with information from the cache.

Implementations

impl<'a, CacheModels: CacheableModels> InMemoryCachePermissions<'a, CacheModels>

pub const fn cache_ref(&'a self) -> &'a InMemoryCache<CacheModels>

Immutable reference to the underlying cache.

pub const fn into_cache(self) -> &'a InMemoryCache<CacheModels>

Consume the statistics interface, returning the underlying cache reference.

pub const fn check_member_communication_disabled( self, check_member_communication_disabled: bool, ) -> Self

Whether to check whether a member’s communication is disabled.

Refer to the module level documentation for information and caveats.

Defaults to being enabled.

pub fn in_channel( &self, user_id: Id<UserMarker>, channel_id: Id<ChannelMarker>, ) -> Result<Permissions, ChannelError>

Calculate the permissions of a member in a guild channel.

Returns Permissions::all if the user is the owner of the guild.

If the member’s communication has been disabled then they will be restricted to read-only permissions. Refer to the module level documentation for more information.

The following ResourceTypes must be enabled:

• ResourceType::CHANNEL
• ResourceType::MEMBER
• ResourceType::ROLE

Examples

use twilight_cache_inmemory::DefaultInMemoryCache;
use twilight_model::id::Id;

let cache = DefaultInMemoryCache::new();

// later on...

let channel_id = Id::new(4);
let user_id = Id::new(5);

let permissions = cache.permissions().in_channel(user_id, channel_id)?;
println!("User {user_id} in channel {channel_id} has permissions {permissions:?}");

Errors

Returns a ChannelErrorType::ChannelUnavailable error type if the guild channel is not in the cache.

Returns a ChannelErrorType::MemberUnavailable error type if the member for the user in the guild is not present.

Returns a ChannelErrorType::RoleUnavailable error type if one of the member’s roles is not in the cache.

pub fn root( &self, user_id: Id<UserMarker>, guild_id: Id<GuildMarker>, ) -> Result<Permissions, RootError>

Calculate the guild-level permissions of a member.

Returns Permissions::all if the user is the owner of the guild.

If the member’s communication has been disabled then they will be restricted to read-only permissions. Refer to the module level documentation for more information.

The following ResourceTypes must be enabled:

• ResourceType::MEMBER
• ResourceType::ROLE

Examples

use twilight_cache_inmemory::DefaultInMemoryCache;
use twilight_model::id::Id;

let cache = DefaultInMemoryCache::new();

// later on...

let guild_id = Id::new(4);
let user_id = Id::new(5);

let permissions = cache.permissions().root(user_id, guild_id)?;
println!("User {user_id} in guild {guild_id} has permissions {permissions:?}");

Errors

Returns a RootErrorType::MemberUnavailable error type if the member for the user in the guild is not present.

Returns a RootErrorType::RoleUnavailable error type if one of the member’s roles is not in the cache.
