Struct ApiCapabilities 

pub struct ApiCapabilities { /* private fields */ }

What an implementation says it is and what it can do.

Reported by the implementation, never inferred by the consumer. The point of checking this at startup is that a missing capability surfaces as a message telling the operator what to update — instead of as a failure inside whatever the consumer was doing when it first needed the capability.

Implementations

impl ApiCapabilities

pub fn contract_version(&self) -> u32

pub fn library_version(&self) -> &str

pub fn supports(&self, capability: &str) -> bool

pub fn capabilities(&self) -> impl Iterator<Item = &str>
