Crate macro_magic_core

This crate contains most of the internal implementation of the macros in the macro_magic_macros crate. For the most part, the proc macros in macro_magic_macros just call their respective _internal variants in this crate.

Structs

AttrItemWithExtra

Used to parse args passed to the inner pro macro auto-generated by import_tokens_attr_internal.

ForwardTokensArgs

Used to parse args that were passed to forward_tokens_internal.

ForwardTokensExtraArg

Used to parse args that were passed to forward_tokens_internal and forward_tokens_inner_internal.

ForwardedTokens

Used to parse args that were passed to forward_tokens_inner_internal.

ImportTokensArgs

Used to parse the args for the import_tokens_internal function.

ImportedTokens

Used to parse the args for the import_tokens_inner_internal function.

ProcMacro

Generically parses a proc macro definition with support for all variants.

Enums

ProcMacroType

Delineates the different types of proc macro

Constants

MACRO_MAGIC_ROOT

Constant used to load the configured location for macro_magic that will be used in generated macro code.

Traits

ForeignPath

Should be implemented by structs that will be passed to #[with_custom_parsing(..)]. Such structs should also implement syn::parse::Parse.

Functions

export_tokens_alias_internal

Internal implementation of export_tokens_alias!. Allows creating a renamed/rebranded macro that does the same thing as #[export_tokens]

export_tokens_internal

The internal code behind the #[export_tokens] attribute macro.

export_tokens_macro_ident

Produces the full path for the auto-generated callback-based decl macro that allows us to forward tokens across crate boundaries.

export_tokens_macro_path

Resolves to the path of the #[export_tokens] macro for the given item path.

flatten_ident

“Flattens” an Ident by converting it to snake case.

forward_tokens_inner_internal

Used by forward_tokens_internal.

forward_tokens_internal

The internal implementation for the forward_tokens macro.

import_tokens_attr_internal

Internal implementation for the #[import_tokens_attr] attribute.

import_tokens_inner_internal

The internal implementation for the import_tokens_inner macro.

import_tokens_internal

The internal implementation for the import_tokens macro.

import_tokens_proc_internal

Internal implementation for the #[import_tokens_proc] attribute.

macro_magic_path

Safely access a subpath of macro_magic

macro_magic_root

Safely access the macro_magic root based on the MACRO_MAGIC_ROOT env var, which defaults to ::macro_magic, but can be configured via the [env] section of .cargo/config.toml

parse_proc_macro_variant

Parses a proc macro function from a TokenStream2 expecting only the specified macro_type

private_path

Safely access a subpath of macro_magic::__private

to_snake_case

Returns the specified string in snake_case

with_custom_parsing_internal

The internal implementation for the #[with_custom_parsing(..) attribute macro.
