pub fn push_write(&mut self, item: T)

Adds a resource to the permissions set as writable.

pub fn remove(&mut self, item: &T)

Removes a resource from the permissions set.

pub fn remove_read(&mut self, item: &T)

Removes read access to a resource from the permissions set.

pub fn remove_write(&mut self, item: &T)

Removes write access to a resource from the permissions set.

pub fn add(&mut self, other: Self)

Adds all of the permissions contained in the given set to this permission set.

pub fn subtract(&mut self, other: &Self)
