Struct GpuBuilder 

pub struct GpuBuilder { /* private fields */ }

Builder for acquiring a fabric GPU lease.

Allows specifying minimum VRAM requirements.

Examples

use grafos_std::gpu::GpuBuilder;

let lease = GpuBuilder::new().min_vram(1024).acquire()?;
// lease.gpu() is available for submit() calls

Implementations

impl GpuBuilder

pub fn new() -> Self

Create a new builder with no VRAM constraint and no exclusivity preference (daemon default applies).

pub fn min_vram(self, n: u64) -> Self

Set the minimum VRAM required in bytes.

pub fn exclusivity(self, class: GpuExclusivityClass) -> Self

Request a specific GPU exclusivity class for this lease.

When set, the daemon emits TLV_LEASE_GPU_EXCLUSIVITY (0x0903) on the LEASE_ALLOC request. When omitted, the daemon’s --gpu-share-mode default applies.

Examples

use grafos_std::gpu::{GpuBuilder, GpuExclusivityClass};

let lease = GpuBuilder::new()
    .min_vram(1024)
    .exclusivity(GpuExclusivityClass::DeviceExclusive)
    .acquire()?;

pub fn affinity(self, a: Affinity) -> Self

Add an affinity constraint (toward the target).

pub fn anti_affinity(self, strength: Strength, target: Target) -> Self

Add an anti-affinity constraint (away from the target).

pub fn lease_secs(self, secs: u32) -> Self

Set the lease TTL in seconds.

pub fn acquire(self) -> Result<GpuLease>

Acquire a GPU lease.

On wasm32, allocates via the gpu_lease_alloc host import. On native, uses the local mock lease allocator.

Errors

Returns crate::error::FabricError::CapacityExceeded or crate::error::FabricError::Disconnected if the host cannot satisfy the request.

Trait Implementations

impl Default for GpuBuilder

fn default() -> Self

Returns the “default value” for a type.
