# ComputeHostVisibilityDecision

Compute host visibility decision.

Last updated: 2026-09-09

Package: compute.buffer | Status: source-declared

Tags: buffer, compute, compute.buffer, cpu, function, source-example, yeho

Describe compute buffer layouts, ownership, transfers, and validation.

```yh
external ComputeHostVisibilityDecision(computeBufferResource resource) returns computeResourceDecision
```


## Use ComputeHostVisibilityDecision

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using compute.buffer

// Describe compute buffer layouts, ownership, transfers, and validation.
computeBufferResource resource = computeBufferResource("id", "device Id", "memory Class", 4, 4, true, true, true, true, 1, "state", "external Identity")
computeResourceDecision result = ComputeHostVisibilityDecision(resource)
Console.Log("Inspect result in your debugger")

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.compute_buffer__computehostvisibilitydecision"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "compute.buffer"
version = "0.1.0"
path = "../../../yeho/packages/compute/buffer"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/compute.buffer--ComputeHostVisibilityDecision/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
