Struct RuleSetDiff 

pub struct RuleSetDiff {
    pub added: Vec<String>,
    pub removed: Vec<String>,
    pub unchanged: usize,
}

Diff between two rule sets.

Fields

added: Vec<String>

Rules present in the new set but absent in the old set.

removed: Vec<String>

Rules present in the old set but absent in the new set.

unchanged: usize

Number of rules that appear in both sets.

Implementations

impl RuleSetDiff

pub fn diff(old_rules: &[String], new_rules: &[String]) -> Self

Compute the diff between old_rules and new_rules.

The added and removed vectors are sorted for determinism.

pub fn is_empty(&self) -> bool

Returns true when there are no additions and no removals.

pub fn summary(&self) -> String

Returns a compact summary string in the form "+A/-R/=U".

Trait Implementations

impl Clone for RuleSetDiff

fn clone(&self) -> RuleSetDiff

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuleSetDiff

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

Formats the value using the given formatter.

impl Display for RuleSetDiff

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

Formats the value using the given formatter.

impl Eq for RuleSetDiff

impl PartialEq for RuleSetDiff

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