Implementations

impl FieldIndex

pub fn to_field_reference(self) -> FieldReference

Convert this field index to a FieldReference for use in expressions.

Trait Implementations

impl Clone for FieldIndex

fn clone(&self) -> FieldIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FieldIndex

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

Formats the value using the given formatter.

impl ParsePair for FieldIndex

fn rule() -> Rule

fn message() -> &'static str

fn parse_pair(pair: Pair<'_, Rule>) -> Self

fn parse_str(s: &str) -> Result<Self, MessageParseError>

impl PartialEq for FieldIndex

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