pub struct ProtocolRegistry { /* private fields */ }

Implementations

impl ProtocolRegistry

pub fn new() -> Self

pub fn register<F>( &mut self, protocol: impl Into<String>, method: impl Into<String>, function: F, )

where F: Fn(&[Value]) -> Result<Value, String> + 'static,

pub fn register_marker<S>(&mut self, protocol: impl Into<String>, supports: S)

where S: Fn(&Value) -> bool + 'static,

pub fn register_when<S, F>( &mut self, protocol: impl Into<String>, method: impl Into<String>, supports: S, function: F, )

where S: Fn(&Value) -> bool + 'static, F: Fn(&[Value]) -> Result<Value, String> + 'static,

pub fn register_extension<F>( &mut self, provider: impl Into<String>, type_name: impl Into<String>, protocol: impl Into<String>, method: impl Into<String>, function: F, )

where F: Fn(&[Value]) -> Result<Value, String> + 'static,

Registers a protocol implementation for one opaque extension type.

Extension methods are kept separate from the ordinary protocol fallback chain so collection primitives can dispatch without recursively entering their own built-in protocol implementation.

pub fn register_extension_category( &mut self, provider: impl Into<String>, type_name: impl Into<String>, category: impl Into<String>, )

Marks an opaque extension type as a logical collection category such as map. Predicates can then preserve the guest-language collection model.

pub fn invoke_extension( &self, receiver: &ExtensionValue, protocol: &str, method: &str, arguments: &[Value], ) -> Result<Value, String>

pub fn extension_has_category( &self, receiver: &ExtensionValue, category: &str, ) -> bool

pub fn register_guest( &self, protocol: impl Into<String>, type_name: impl Into<String>, method: impl Into<String>, function: Rc<Function>, )

pub fn declare_guest( &self, protocol: impl Into<String>, method: impl Into<String>, )

pub fn register_guest_protocol(&self, protocol: Rc<GuestProtocol>)

pub fn guest_protocol_reaches(&self, source: &str, target: &str) -> bool

pub fn replace_guest_protocol(&self, protocol: impl Into<String>)

pub fn invoke( &self, protocol: &str, method: &str, arguments: &[Value], ) -> Result<Value, String>

pub fn contains(&self, protocol: &str, method: &str) -> bool

pub fn satisfies(&self, protocol: &GuestProtocol, value: &Value) -> bool

pub fn core() -> Self

Returns the built-in collection protocol registry used by evaluator dispatch.
