A statement in the C programming language. This may not be exact to what an AST would look like or what the C standard says about the C language, it’s simply a structed way to organize data for generating C code.

Variants

Declaration

A declaration of some kind.

Fields

name: String

The name of the thing being declared.

is_extern: bool

Whether the thing being declared is extern.

is_const: bool

Whether the thing being declared is const.

ctype: CType

The type of the thing being declared.

definition: Option<Box<CStatement>>

The definition of the thing being declared.

This is useful for initializing constant arrays, for example.

LiteralArray

Fields

items: Vec<CStatement>

The contents of the array.

LiteralConstant

A literal constant value, passed through directly as a string.

Fields

value: String

The raw value acting as a constant.

Cast

A C-style cast

Fields

target_type: CType

The type to cast to.

expression: Box<CStatement>

The thing being cast.

TypeDef

Typedef one type to another.

Fields

source_type: CType

The type of the thing being typedef’d.

new_name: String

The new name by which this type may be called.
