Struct ErrorPattern 

pub struct ErrorPattern {
    pub id: String,
    pub keywords: Vec<String>,
    pub fix: FixAction,
    pub applications: usize,
    pub successes: usize,
    pub source: PatternSource,
}

Error pattern with learned success rate

Fields

id: String

Pattern identifier

keywords: Vec<String>

Keywords that match this error

fix: FixAction

Suggested fix action

applications: usize

Number of times pattern was applied

successes: usize

Number of successful fixes

source: PatternSource

Source of pattern (bootstrap, llm, corpus)

Implementations

impl ErrorPattern

pub fn new(id: impl Into<String>, keywords: Vec<String>, fix: FixAction) -> Self

Create new error pattern

pub fn success_rate(&self) -> f32

Calculate success rate

pub fn should_retire(&self) -> bool

Check if pattern should be retired

Per spec: “Patterns with <30% success rate after 5 applications are automatically retired.”

pub fn record_application(&mut self, success: bool)

Record application of this pattern

pub fn matches(&self, error_message: &str) -> bool

Check if error message matches this pattern

pub fn match_confidence(&self, error_message: &str) -> f32

Calculate match confidence (0.0 - 1.0)

Trait Implementations

impl Clone for ErrorPattern

fn clone(&self) -> ErrorPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorPattern

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

Formats the value using the given formatter.
