Struct ImpactScore 

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

Validated impact score representing error severity (0-1000).

Purpose

This newtype centralizes impact validation and makes the type system encode security policy:

• Impact scores must be in valid range (0-1000)
• Construction enforces validation once at creation
• Downstream consumers receive pre-validated scores

Copy Semantics

This type is Copy because:

• It’s a small numeric value (u16)
• No governance risk from duplication
• Defensive code benefits from pass-by-value semantics

Feature: Strict Severity Authority

When strict_severity feature is enabled, additional constraints apply based on namespace authority flags. See ErrorNamespace::CAN_BREACH.

Example

// Compile-time validation
const MINOR_IMPACT: ImpactScore = ImpactScore::new(150);

// Runtime validation
let score = ImpactScore::checked_new(user_input).unwrap();

Implementations

impl ImpactScore

pub const fn new(score: u16) -> Self

Create a new impact score with compile-time validation.

Panics

Panics at compile time (in const contexts) if score > 1000. Panics at runtime (in non-const contexts) if score > 1000.

Use Case

For const static error code definitions where scores are known at compile time.

pub fn checked_new(score: u16) -> Result<Self, ImpactScoreError>

Create a new impact score with runtime validation.

Errors

Returns Err if score > 1000.

Use Case

For runtime paths where impact scores come from configuration, user input, or dynamic sources. Prevents panics.

pub const fn value(self) -> u16

Get the raw numeric value.

pub const fn to_impact_level(self) -> ErrorImpact

Convert to detailed impact level classification.

pub const fn is_breach_level(self) -> bool

Check if this is a Breach-level impact (951-1000).

Trait Implementations

impl Clone for ImpactScore

fn clone(&self) -> ImpactScore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImpactScore

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

Formats the value using the given formatter.

impl Display for ImpactScore

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

Formats the value using the given formatter.

impl Hash for ImpactScore

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 PartialEq for ImpactScore

fn eq(&self, other: &ImpactScore) -> 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.
