Struct Line 

pub struct Line { /* private fields */ }

Zero-copy line representation that points directly into memory-mapped data

Implementations

impl Line

pub fn new(data: &[u8]) -> Self

Create a new Line from a slice

pub unsafe fn as_bytes(&self) -> &[u8]

Get the line data as a byte slice

Safety

The caller must ensure that:

1. The memory this Line points to is still valid (not freed)
2. The memory-mapped file has not been unmapped
3. No other code is mutating this memory region

pub fn extract_field( &self, field_num: usize, separator: Option<char>, ) -> Option<&[u8]>

Extract a field from the line based on field separator Fields are 1-indexed (field 1 is the first field)

pub fn extract_key( &self, key: &SortKey, separator: Option<char>, ) -> Option<&[u8]>

Extract a key region from the line based on SortKey specification

pub fn parse_int(&self) -> Option<i64>

Fast numeric parsing for simple integers (optimized path)

pub fn parse_general_numeric(&self) -> f64

Parse as general numeric (supports scientific notation, inf, nan)

pub fn compare_general_numeric(&self, other: &Line) -> Ordering

Compare as general numeric values (scientific notation support)

pub fn compare_with_keys( &self, other: &Line, keys: &[SortKey], separator: Option<char>, config: &SortConfig, ) -> Ordering

Compare lines using field-based sorting with multiple keys

pub fn compare_with_config(&self, other: &Line, config: &SortConfig) -> Ordering

Compare lines based on global configuration (when no keys are specified)

pub fn compare_numeric(&self, other: &Line) -> Ordering

Fast comparison for numeric values (GNU sort style - no string conversion)

pub fn len(&self) -> usize

Get the length of the line

pub fn is_empty(&self) -> bool

Check if the line is empty

pub fn compare_ignore_case(&self, other: &Line) -> Ordering

Locale-aware case-insensitive comparison

pub fn compare_lexicographic(&self, other: &Line) -> Ordering

Locale-aware lexicographic comparison

pub fn compare_lexicographic_with_blanks( &self, other: &Line, ignore_leading_blanks: bool, ) -> Ordering

Lexicographic comparison with option to ignore leading blanks

pub fn compare_dictionary_order(&self, other: &Line) -> Ordering

Dictionary order comparison (only alphanumeric characters and blanks)

pub fn compare_dictionary_order_ignore_case(&self, other: &Line) -> Ordering

Dictionary order with case-insensitive comparison

pub fn compare_month(&self, other: &Line) -> Ordering

Month-aware comparison (GNU sort compatible)

pub fn compare_version(&self, other: &Line) -> Ordering

Version-aware comparison (GNU sort -V compatible)

pub fn compare_human_numeric(&self, other: &Line) -> Ordering

Human numeric comparison (GNU sort -h compatible)
