Example
mkCancellable [RpcEncodable β] (handler : α → RequestM (RequestTask β)) :
α → RequestM (RequestTask RequestId)
fun a => do
RequestM.asTask do
let t ← handler a
let t' := t.mapCheap (·.map rpcEncode)
runningRequests.modifyGet fun (id, m) =>
(id, (id+1, m.insert id ⟨t'.task, t.cancel⟩))
- type: def | symbolic_name:
ProofWidgets.mkCancellable| ProofWidgets/Cancellable.lean
Use
Each declaration is split into a statement (signature/claim) and a proof (body) that are disjoint
and together form the complete declaration, for proof modeling, autoformalization, retrieval, and
dependency analysis via deps.
