Struct Record 

pub struct Record {
    pub uid: Uuid,
    /* private fields */
}

Represents a processed log record.

A Record consists of a TokenStream (the tokenized log line) and a unique identifier (Uuid).

Fields

uid: Uuid

Implementations

impl Record

pub fn new(line: String) -> Self

Creates a new Record from a given log line string.

This involves tokenizing the line and generating a new UUID (version 1) for the record.

Arguments

• line - The raw log line as a String.

Returns

A new Record instance.

pub fn calc_sim_score(&self, candidate: &Record) -> u64

Calculates a similarity score between this Record (acting as a template) and a candidate Record.

The score is the number of matching tokens between the two records. A Token::Wildcard in the template matches any token in the candidate.

Arguments

• candidate - The Record to compare against this record.

Returns

The similarity score as a u64.

pub fn first(&self) -> Option<DefaultSymbol>

Returns the first token of the record’s TokenStream.

Returns

An Option<DefaultSymbol> containing the first token if it exists, otherwise None.

pub fn len(&self) -> usize

Returns the number of tokens in the record’s TokenStream.

Returns

The length of the token stream as a usize.

pub fn is_empty(&self) -> bool

Checks if the record’s TokenStream is empty.

Returns

true if the token stream is empty, false otherwise.

pub fn resolve(sym: DefaultSymbol) -> Option<String>

Resolves a DefaultSymbol back to its original string representation.

This is a utility method that uses the global string interner to retrieve the string associated with a given symbol.

Arguments

• sym - The DefaultSymbol to resolve.

Returns

An Option<String> containing the resolved string if the symbol exists, otherwise None.

Trait Implementations

impl Clone for Record

fn clone(&self) -> Record

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Record

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

Formats the value using the given formatter.

impl Display for Record

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

Formats the Record for display.

This implementation reconstructs the original log line from the TokenStream, preserving whitespace.

Arguments

• f - The formatter to write into.

Returns

A fmt::Result indicating success or failure of the formatting operation.

impl IntoIterator for Record

type IntoIter = IntoIter

Which kind of iterator are we turning this into?

type Item = String

The type of the elements being iterated over.

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a> IntoIterator for &'a Record

type Item = &'a Token

The type of the elements being iterated over.

type IntoIter = Map<Iter<'a, (Offset, Token)>, fn(&(Offset, Token)) -> &Token>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
