pub struct Permissions { /* private fields */ }
Expand description

A collection of allowed permissions. This is constructed from a Vec<Statement>. By default, no actions are allowed on any resources.

Implementations§

§

impl Permissions

pub fn allow_all() -> Permissions

Returns a Permisions instance constructed with Statement::allow_all().

pub fn check<'a, R, P>( &self, resource_name: R, action: &P ) -> Result<(), PermissionDenied>where R: AsRef<[Identifier<'a>]>, P: Action,

Evaluate whether the action is allowed to be taken upon resource_name. Returns Ok if permission is allowed.

Errors

Returns PermissionDenied if permission is now allowed.

pub fn allowed_to<'a, R, P>(&self, resource_name: R, action: &P) -> boolwhere R: AsRef<[Identifier<'a>]>, P: Action,

Evaluate whether the action is allowed to be taken upon resource_name. Returns true if the action should be allowed. If no statements that match resource_name allow action, false will be returned.

pub fn get<'a, 's, R>( &'s self, resource_name: R, key: &str ) -> Option<&'s Configuration>where 'a: 's, R: AsRef<[Identifier<'a>]>,

Looks up a configured value for resource_name.

pub fn merged<'a>( permissions: impl IntoIterator<Item = &'a Permissions> ) -> Permissions

Returns a new instance that merges all allowed actions from permissions.
