Struct Capabilities 

pub struct Capabilities { /* private fields */ }

What a target offers beyond the contract’s obligations. Built with setters from Capabilities::NONE; the fields are private, so a capability added later is not a breaking change.

Implementations

impl Capabilities

pub const NONE: Capabilities

Nothing beyond the obligations.

pub const fn with_write_through(self) -> Capabilities

The target honours a write’s WriteCaching::WriteThrough.

pub const fn write_through(&self) -> bool

Whether the target honours a write’s WriteCaching::WriteThrough.
