Struct NetBuilder 

pub struct NetBuilder { /* private fields */ }

Builder for acquiring a fabric network lease.

Allows specifying minimum bandwidth requirements.

Examples

use grafos_std::net::NetBuilder;

let lease = NetBuilder::new().min_bandwidth(1_000_000_000).acquire()?;
assert!(lease.net().bandwidth() >= 1_000_000_000);

Implementations

impl NetBuilder

pub fn new() -> Self

Create a new builder with no bandwidth constraint.

pub fn min_bandwidth(self, bps: u64) -> Self

Set the minimum bandwidth required in bits per second.

pub fn lease_secs(self, secs: u64) -> Self

Set the lease TTL in seconds.

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

Acquire a network lease.

Calls the host net_hello function with the requested minimum bandwidth. The host allocates a NIC (macvlan or SR-IOV VF) and returns the interface name and actual bandwidth.

Errors

Returns FabricError::CapacityExceeded if the host cannot satisfy the bandwidth requirement, or FabricError::Disconnected if the host connection fails.

Trait Implementations

impl Default for NetBuilder

fn default() -> Self

Returns the “default value” for a type.
