Enum SourceKey 

pub enum SourceKey {
    Ident(Identifier),
    Extension(Identifier),
    String(String, StringStyle),
    Integer(i64),
    Tuple(Vec<SourceKey>),
    TupleIndex(u8),
}

A key in source representation.

This determines how the key should be rendered in the output.

Variants

Ident(Identifier)

Bare identifier: foo, bar_baz

Extension(Identifier)

Extension namespace: $variant, $eure

String(String, StringStyle)

String key with syntax style hint.

• StringStyle::Quoted: "hello world"
• StringStyle::Literal: 'hello world'

Note: PartialEq ignores the style - only content matters for equality.

Integer(i64)

Integer key: 123

Tuple(Vec<SourceKey>)

Tuple key: (1, "a")

TupleIndex(u8)

Tuple index: #0, #1

Implementations

impl SourceKey

pub fn quoted(s: impl Into<String>) -> Self

Create a quoted string key: "..."

pub fn literal(s: impl Into<String>) -> Self

Create a literal string key (single-quoted): '...'

pub fn delimited_lit_str(s: impl Into<String>, level: u8) -> Self

Create a delimited literal string key: <'...'>, <<'...'>>, <<<'...'>>>

pub fn delimited_code(s: impl Into<String>, level: u8) -> Self

Create a delimited code key: <…>, <<…>>, <<<…>>>

Trait Implementations

impl Clone for SourceKey

fn clone(&self) -> SourceKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceKey

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

Formats the value using the given formatter.

impl From<Identifier> for SourceKey

fn from(id: Identifier) -> Self

Converts to this type from the input type.

impl From<i64> for SourceKey

fn from(n: i64) -> Self

Converts to this type from the input type.

impl PartialEq for SourceKey

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