pub struct Permissions<T: PartialEq> { /* fields omitted */ }

Describes read and write access to resources.

Implementations

impl<T: PartialEq> Permissions<T>

pub fn new() -> Self

Constructs a new empty permissions set.

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

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

Adds a resource to the permissions set as readable.

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)

Subtracts all of the permissions contained in the given set from this permission set.

pub fn reads(&self) -> &[T]

Gets a slice of resources which are afforded read access.

pub fn writes(&self) -> &[T]
