Struct Counter 

pub struct Counter { /* private fields */ }

A handle to a cFE generic counter.

The counter can be shared across tasks. The underlying cFE resource is automatically deleted when the Counter is dropped.

Implementations

impl Counter

pub fn new(name: &str) -> Result<Self>

Registers a new generic counter with cFE.

The counter is initialized to 0.

Arguments

• name: A unique string to identify the counter.

pub fn inc(&self) -> Result<()>

Increments the counter’s value by one.

Note: the C header does not guarantee atomicity for this operation.

pub fn set(&self, count: u32) -> Result<()>

Sets the counter’s value to a specific number.

pub fn get(&self) -> Result<u32>

Retrieves the current value of the counter.

pub fn id(&self) -> CounterId

Returns the underlying cFE ID of the counter.

pub fn get_id_by_name(name: &str) -> Result<CounterId>

Gets the cFE ID for a generic counter by its registered name.

Trait Implementations

impl Debug for Counter

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

Formats the value using the given formatter.

impl Drop for Counter

fn drop(&mut self)

Deletes the generic counter when the Counter object goes out of scope.
