Struct RecordRef 

pub struct RecordRef {
    pub line: Option<usize>,
    pub record_index: Option<usize>,
    pub satellite: Option<String>,
}

A reference to a record in an input stream.

Fields

line: Option<usize>

The one-based input line number, when known.

record_index: Option<usize>

The zero- or one-based logical record index chosen by the caller.

satellite: Option<String>

A raw satellite token, when known.

Implementations

impl RecordRef

pub fn at_line(line: usize) -> Self

Build a record reference at a one-based line number.

pub fn at_record(record_index: usize) -> Self

Build a record reference at a logical record index.

pub fn with_satellite(self, satellite: impl Into<String>) -> Self

Attach a raw satellite token to this reference.

Trait Implementations

impl Clone for RecordRef

fn clone(&self) -> RecordRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecordRef

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

Formats the value using the given formatter.

impl Default for RecordRef

fn default() -> RecordRef

Returns the “default value” for a type.

impl PartialEq for RecordRef

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