Struct EpochBumper 

Source 
pub struct EpochBumper { /* private fields */ }
Expand description

Cooperative cancel handle for an in-flight eval. Wraps a clone of the Session’s [wasmtime::Engine]; the engine’s epoch counter is shared internally so a .bump() from any task takes effect on the concurrent func.call_async running against the same engine.

Each Session sets store.set_epoch_deadline(1) before invoking nomi-eval, so one bump trips the deadline and the eval traps with wasmtime::Trap::Interrupt — surfaced upstream as EngineError::EpochInterrupt and on the wire as (:error (:code interrupted ...)).

Implementations§

Source§

impl EpochBumper

Source

pub fn bump(&self)

Increments the engine epoch. Returns immediately (no await). Safe to call before, during, or after an eval; the next epoch check inside any in-flight call_async traps.
