Struct TotalCount 

pub struct TotalCount(/* private fields */);

Total count newtype

Poka-Yoke: Use this newtype instead of usize to prevent count errors. Ensures total count is always >= 0 and >= covered count.

Example

use chicago_tdd_tools::coverage::{TotalCount, CoveredCount};

let total = TotalCount::new(100).unwrap();
let covered = CoveredCount::new(80).unwrap();

// Validate: covered <= total
assert!(covered.get() <= total.get());
assert_eq!(total.get(), 100);
assert_eq!(covered.get(), 80);

Implementations

impl TotalCount

pub const ZERO: Self

Zero total count constant

Poka-Yoke: Infallible constructor - no Option wrapping needed. Use this instead of TotalCount::new(0).unwrap().

pub const fn new(value: usize) -> Option<Self>

Create a new total count (legacy API - prefer from_usize)

Note: This always returns Some. For infallible construction, use from_usize().

pub const fn from_usize(value: usize) -> Self

Create a new total count (infallible)

Poka-Yoke: Infallible constructor - use this instead of .new().unwrap(). Any usize value is valid for total count.

pub const fn get(&self) -> usize

Get the count value

pub const fn into_usize(self) -> usize

Convert to usize

Trait Implementations

impl Clone for TotalCount

fn clone(&self) -> TotalCount

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TotalCount

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

Formats the value using the given formatter.

impl From<TotalCount> for usize

fn from(count: TotalCount) -> Self

Converts to this type from the input type.

impl Hash for TotalCount

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TotalCount

fn cmp(&self, other: &TotalCount) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TotalCount

fn eq(&self, other: &TotalCount) -> 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 PartialOrd for TotalCount

fn partial_cmp(&self, other: &TotalCount) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
