Expand description

A set of capabilities

Implementations

source

impl Capabilities

source

pub fn none() -> Self

Return an object representing an empty set of capabilities.

source

pub fn all() -> Self

Return an object representing all capabilities enabled.

source

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!).

source

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

Check if particular capability is enabled.

source

pub fn has_all(&self) -> bool

Check if this capability object represents all capabilities.
