Struct FakeHostProbe 

pub struct FakeHostProbe { /* private fields */ }

A host probe that returns pre-configured host information.

This is useful for testing code that depends on HostProbe without actually querying system information.

Thread Safety

All configuration methods are &self (not &mut self), making it safe to share a single instance across multiple threads in tests.

Example

use perfgate_fake::FakeHostProbe;
use perfgate_adapters::{HostProbe, HostProbeOptions};
use perfgate_types::HostInfo;

let probe = FakeHostProbe::new()
    .with_os("linux")
    .with_arch("x86_64")
    .with_cpu_count(8)
    .with_memory_bytes(16 * 1024 * 1024 * 1024);

let options = HostProbeOptions { include_hostname_hash: false };
let info = probe.probe(&options);

assert_eq!(info.os, "linux");
assert_eq!(info.arch, "x86_64");
assert_eq!(info.cpu_count, Some(8));

Implementations

impl FakeHostProbe

pub fn new() -> Self

Create a new FakeHostProbe with default values.

Defaults:

• os: “unknown”
• arch: “unknown”
• cpu_count: None
• memory_bytes: None
• hostname_hash: None (always, unless explicitly set)

pub fn platform(os: &str, arch: &str, cpu_count: u32, memory_bytes: u64) -> Self

Create a FakeHostProbe that mimics a specific platform.

Example

use perfgate_fake::FakeHostProbe;

// Create a probe that looks like a Linux system
let probe = FakeHostProbe::platform("linux", "x86_64", 8, 16 * 1024 * 1024 * 1024);

pub fn with_os(self, os: &str) -> Self

Set the OS string.

pub fn with_arch(self, arch: &str) -> Self

Set the architecture string.

pub fn with_cpu_count(self, count: u32) -> Self

Set the CPU count.

pub fn with_memory_bytes(self, bytes: u64) -> Self

Set the memory in bytes.

pub fn with_hostname_hash(self, hash: &str) -> Self

Set the hostname hash directly.

Note: This overrides the include_hostname_hash option behavior. If set, this value is always returned.

pub fn without_cpu_count(self) -> Self

Set CPU count to None.

pub fn without_memory(self) -> Self

Set memory to None.
