Struct kernel::configfs::Group

source · 
pub struct Group<Data> { /* private fields */ }
Expand description

A configfs group.

To add a subgroup to configfs, pass this type as ctype to crate::configfs_attrs when creating a group in GroupOperations::make_group.

Implementations§

source§

impl<Data> Group<Data>

source

pub fn new( name: CString, item_type: &'static ItemType<Group<Data>, Data>, data: impl PinInit<Data, Error> ) -> impl PinInit<Self, Error>

Create an initializer for a new group.

When instantiated, the group will appear as a directory with the name given by name and it will contain attributes specified by item_type.
