Module symbol 

An “interner” is a data structure that associates values with usize tags and allows bidirectional lookup; i.e., given a value, one can easily find the type, and vice versa.

Modules

kw

This module contains all the defined keyword Symbols.

sym

This module contains all the defined non-keyword Symbols.

Structs

ByteSymbol

Like Symbol, but for byte strings. ByteSymbol is used less widely, so it has fewer operations defined than Symbol.

Ident

IdentPrinter

The most general type to print identifiers.

Interner 🔒

InternerInner 🔒

MacroRulesNormalizedIdent

A newtype around Ident that calls Ident::normalize_to_macro_rules on construction for “local variable hygiene” comparisons.

Symbol

An interned UTF-8 string.

SymbolIndex 🔒

Enums

IdentPrintMode

Constants

PREDEFINED_SYMBOLS_COUNT

The number of predefined symbols; this is the first index for extra pre-interned symbols in an Interner created via Interner::with_extra_symbols.

STDLIB_STABLE_CRATES

Symbols for crates that are part of the stable standard library: std, core, alloc, and proc_macro.

SYMBOL_DIGITS_BASE 🔒

SYMBOL_LOWERCASE_LETTERS_BASE 🔒

SYMBOL_UPPERCASE_LETTERS_BASE 🔒

Functions

used_keywords

Collect all the keywords in a given edition into a vector.
