Struct SystemInfo 

pub struct SystemInfo { /* private fields */ }

System information from device telemetry.

Contains read-only diagnostic data like uptime and network status. These values change frequently and do not trigger callbacks when updated.

Data Sources

• MQTT telemetry: uptime and wifi_rssi from tele/<topic>/STATE
• HTTP status: All fields from Status 0 command

Examples

use std::time::Duration;
use tasmor_lib::state::SystemInfo;

let info = SystemInfo::new()
    .with_uptime(Duration::from_secs(172800))
    .with_wifi_rssi(-60)
    .with_heap(25000);

assert_eq!(info.uptime(), Some(Duration::from_secs(172800)));

Implementations

impl SystemInfo

pub fn new() -> Self

Creates a new empty system info.

pub fn with_uptime(self, duration: Duration) -> Self

Sets the uptime.

Examples

use std::time::Duration;
use tasmor_lib::state::SystemInfo;

let info = SystemInfo::new().with_uptime(Duration::from_secs(86400));
assert_eq!(info.uptime(), Some(Duration::from_secs(86400)));

pub fn with_wifi_rssi(self, rssi: i8) -> Self

Sets the Wi-Fi RSSI in dBm.

pub fn with_heap(self, heap_kb: u32) -> Self

Sets the free heap memory in kilobytes.

pub fn uptime(&self) -> Option<Duration>

Returns the device uptime.

Examples

use std::time::Duration;
use tasmor_lib::state::SystemInfo;

let info = SystemInfo::new().with_uptime(Duration::from_secs(172800));

let uptime = info.uptime().unwrap();
println!("Uptime: {} days", uptime.as_secs() / 86400);

pub fn wifi_rssi(&self) -> Option<i8>

Returns the Wi-Fi signal strength in dBm.

Typical values range from -100 (weak) to 0 (strongest). A signal of -50 dBm or better is considered excellent.

pub fn heap(&self) -> Option<u32>

Returns the free heap memory in kilobytes.

pub fn merge(&mut self, other: &SystemInfo)

Updates fields from another SystemInfo, preserving existing values when the new value is None.

pub fn is_empty(&self) -> bool

Returns true if all fields are None.

Trait Implementations

impl Clone for SystemInfo

fn clone(&self) -> SystemInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SystemInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SystemInfo

fn default() -> SystemInfo

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SystemInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SystemInfo

fn eq(&self, other: &SystemInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SystemInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
