Struct HostPort 

pub struct HostPort<'a> { /* private fields */ }

A single graph->host port, providing typed polling and convenience helpers.

Implementations

impl<'a> HostPort<'a>

pub fn name(&self) -> &'a str

pub fn resolved_type(&self) -> Option<&'a TypeExpr>

The resolved graph->host port type (after planner inference), if known.

pub fn can_type_to<T: HostPollable>(&self) -> bool

Alias for can_poll (terminology: “can this port be typed/popped as T?”).

pub fn can_poll<T: HostPollable>(&self) -> bool

Returns true if this port can be pulled as T without additional user glue.

pub fn is_type_expr(&self, ty: &TypeExpr) -> bool

pub fn try_pop<T: HostPollable>(&self) -> Result<Option<(u64, T)>, NodeError>

Try to pop a single value from this port and decode it as T.

pub fn try_pop_any<T: Any + Clone>(&self) -> Option<(u64, T)>

Pop and attempt to downcast directly from Any without going through Value.
