pub struct ContextAccessRights { /* private fields */ }

Access rights for a given runtime context.

Implementations

impl ContextAccessRights

pub fn new<T: IntoIterator<Item = URef>>(context_key: Key, uref_iter: T) -> Self

Creates a new instance of access rights from an iterator of URefs merging any duplicates, taking the union of their rights.

pub fn context_key(&self) -> Key

Returns the current context key.

pub fn extend(&mut self, urefs: &[URef])

Extends the current access rights from a given set of URefs.

pub fn has_access_rights_to_uref(&self, uref: &URef) -> bool

Checks whether given uref has enough access rights.

pub fn grant_access(&mut self, uref: URef) -> GrantedAccess

Grants access to a URef; unless access was pre-existing.

pub fn remove_access( &mut self, uref_addr: URefAddr, access_rights: AccessRights )

Remove access for a given URef.

Trait Implementations

impl Debug for ContextAccessRights

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<ContextAccessRights> for ContextAccessRights

fn eq(&self, other: &ContextAccessRights) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
