Struct MetricCounter 

pub struct MetricCounter { /* private fields */ }

Monotonically increasing counter (atomic u64).

Counters only go up — use them for totals like “operations completed” or “bytes transferred”. Thread-safe via relaxed atomic operations.

Examples

use grafos_observe::MetricCounter;

let c = MetricCounter::new();
c.inc();
c.add(10);
assert_eq!(c.get(), 11);

let prev = c.reset();
assert_eq!(prev, 11);
assert_eq!(c.get(), 0);

Implementations

impl MetricCounter

pub const fn new() -> Self

Create a new counter starting at zero.

pub fn inc(&self)

Increment the counter by one.

pub fn add(&self, n: u64)

Increment the counter by n.

pub fn get(&self) -> u64

Read the current counter value.

pub fn reset(&self) -> u64

Reset the counter to zero. Returns the previous value.

Trait Implementations

impl Default for MetricCounter

fn default() -> Self

Returns the “default value” for a type.
