Required Methods

fn run(&mut self, inputs: TVec<TValue>) -> TractResult<TVec<TValue>>

fn runnable(&self) -> &dyn Runnable

Provided Methods

fn resolve_symbol(&mut self, symbol: &Symbol, value: i64) -> TractResult<()>

Pin a symbol for the coming turn. A pulsed plan needs the stream length on the turn carrying the last, partial pulse: the input tensor is padded to a full pulse, so its shape can not carry it.

fn seat(&mut self, seating: Seating) -> TractResult<()>

Seat the lanes carrying the coming turn’s streams, one lane per row of axis 0 of its tensors. A turn seating more than one lane needs axis 0 of every stateful node to be the model’s batch axis.

fn reset_lanes(&mut self, lanes: &[LaneId]) -> TractResult<()>

Drop the session state lanes hold, handing them to new streams.

fn input_count(&self) -> usize

fn output_count(&self) -> usize

Implementations

impl dyn State

pub fn is<__T: State>(&self) -> bool

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T: State>(self: Box<Self>) -> Result<Box<__T>, Box<Self>>

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn’t.

pub fn downcast_rc<__T: State>(self: Rc<Self>) -> Result<Rc<__T>, Rc<Self>>

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

pub fn downcast_ref<__T: State>(&self) -> Option<&__T>

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_mut<__T: State>(&mut self) -> Option<&mut __T>

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
