Struct Capabilities

pub struct Capabilities(/* private fields */);

A set of capabilities

Implementations

impl Capabilities

pub fn none() -> Self

Return an object representing an empty set of capabilities.

pub fn all() -> Self

Return an object representing all capabilities enabled.

pub fn rich_offchain_call() -> Self

Return capabilities for rich offchain calls.

Those calls should be allowed to sign and submit transactions and access offchain workers database (but read only!).

pub fn has(&self, capability: Capability) -> bool

Check if particular capability is enabled.

pub fn has_all(&self) -> bool

Check if this capability object represents all capabilities.

Trait Implementations

impl Clone for Capabilities

fn clone(&self) -> Capabilities

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Capabilities

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

Formats the value using the given formatter.

impl<'a> From<&'a [Capability]> for Capabilities

fn from(list: &'a [Capability]) -> Self

Converts to this type from the input type.

impl PartialEq for Capabilities

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

Tests for self and other values to be equal, and is used by ==.

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

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