Module macros 

Macros

c_enum 🔒

Represent a C enum as Rust constants and a type.

cfg_if 🔒

A macro for defining #cfg if-else statements.

custom_struct 🔒

Emit a struct with the given derive attributes plus a generated Default impl. Ensure that the record has an additional private field added to replicate #[non_exhaustive], unless it is annotated with #[exhaustive].

deprecated_mach 🔒

e 🔒

Implement Clone and Copy for an enum, as well as Debug, Eq, Hash, and PartialEq if the extra_traits feature is enabled.

emit_struct_default_body 🔒

Expands the Default implementation of the record defined at [custom_struct], with either one of an additional private field initialized to the unit value, or the record’s fields verbatim.

emit_struct_definition 🔒

Expands the definition of the record defined at [custom_struct], with either one of an additional private field or with its verbatim fields.

emit_union_default_via_unsafe_zeroed 🔒

Add a Default impl that is just mem::zeroed.

extern_ty 🔒

Create an uninhabited type that can’t be constructed. It implements Debug, Clone, and Copy, but these aren’t meaningful for extern types so they should eventually be removed.

f 🔒

Define a function that can be either safe or unsafe and optionally const. This always marks the function inline and adds extern "C".

offset_of 🔒

Polyfill for std’s offset_of.

prelude 🔒

Create an internal crate prelude with core reexports and common types.

s 🔒

Implement Clone, Copy, and Debug for one or more structs, as well as PartialEq, Eq, and Hash if the extra_traits feature is enabled.

s2 🔒

Like s, but (1) generates a Default impl for every struct in the block, and (2) adds a private field to the struct to replicate the effects of the non_exhaustive attribute while rust-lang/rust#132699 gets sorted out.

s_no_extra_traits 🔒

Implement Clone, Copy, and Debug for one or more structs/unions, but exclude PartialEq, Eq, and Hash.

s_no_extra_traits2 🔒

Like [s_no_extra_traits], but (1) generates a Default impl for every struct in the block, and (2) adds a private field to replicate the effects of the built-in non_exhaustive attribute while rust-lang/rust#132699 gets sorted out.

s_paren 🔒

Implement Clone, Copy, and Debug for a tuple struct, as well as PartialEq, Eq, and Hash if the extra_traits feature is enabled.

union_with_debug 🔒

Emit a union plus its Debug impl.
