  1. dBusInterfaceInfoLookupSignal :: (HasCallStack, MonadIO m) => DBusInterfaceInfo -> Text -> m (Maybe DBusSignalInfo)

    gi-gio GI.Gio.Structs.DBusInterfaceInfo

    Looks up information about a signal. The cost of this function is O(n) in number of signals unless dBusInterfaceInfoCacheBuild has been used on info. Since: 2.26

  2. dBusNodeInfoLookupInterface :: (HasCallStack, MonadIO m) => DBusNodeInfo -> Text -> m (Maybe DBusInterfaceInfo)

    gi-gio GI.Gio.Structs.DBusNodeInfo

    Looks up information about an interface. The cost of this function is O(n) in number of interfaces. Since: 2.26

  3. fileAttributeInfoListLookup :: (HasCallStack, MonadIO m) => FileAttributeInfoList -> Text -> m FileAttributeInfo

    gi-gio GI.Gio.Structs.FileAttributeInfoList

    Gets the file attribute with the name name from list.

  4. iOExtensionPointLookup :: (HasCallStack, MonadIO m) => Text -> m IOExtensionPoint

    gi-gio GI.Gio.Structs.IOExtensionPoint

    Looks up an existing extension point.

  5. resourceLookupData :: (HasCallStack, MonadIO m) => Resource -> Text -> [ResourceLookupFlags] -> m Bytes

    gi-gio GI.Gio.Structs.Resource

    Looks for a file at the specified path in the resource and returns a Bytes that lets you directly access the data in memory. The data is always followed by a zero byte, so you can safely use the data as a C string. However, that byte is not included in the size of the GBytes. For uncompressed resource files this is a pointer directly into the resource bundle, which is typically in some readonly data section in the program binary. For compressed files we allocate memory on the heap and automatically uncompress the data. lookupFlags controls the behaviour of the lookup. Since: 2.32

  6. settingsSchemaSourceLookup :: (HasCallStack, MonadIO m) => SettingsSchemaSource -> Text -> Bool -> m (Maybe SettingsSchema)

    gi-gio GI.Gio.Structs.SettingsSchemaSource

    Looks up a schema with the identifier schemaId in source. This function is not required for normal uses of Settings but it may be useful to authors of plugin management systems or to those who want to introspect the content of schemas. If the schema isn't found directly in source and recursive is True then the parent sources will also be checked. If the schema isn't found, Nothing is returned. Since: 2.32

  7. ssLookupFile :: StaticSettings -> Pieces -> IO LookupResult

    wai-app-static Network.Wai.Application.Static

    Lookup a single file or folder. This is how you can control storage backend (filesystem, embedded, etc) and where to lookup.

  8. webAppSettingsWithLookup :: FilePath -> ETagLookup -> StaticSettings

    wai-app-static Network.Wai.Application.Static

    Same as defaultWebAppSettings, but additionally uses a specialized ETagLookup in place of the standard one. This can allow you to cache your hash values, or even precompute them.

  9. type ETagLookup = FilePath -> IO Maybe ByteString

    wai-app-static WaiAppStatic.Storage.Filesystem

    How to calculate etags. Can perform filesystem reads on each call, or use some caching mechanism.

  10. webAppSettingsWithLookup :: FilePath -> ETagLookup -> StaticSettings

    wai-app-static WaiAppStatic.Storage.Filesystem

    Same as defaultWebAppSettings, but additionally uses a specialized ETagLookup in place of the standard one. This can allow you to cache your hash values, or even precompute them.
