Struct Compiler

pub struct Compiler<'src> { /* private fields */ }

A compiler for the dice syntax tree, capable of walking the syntax tree and generating intermediate representation (IR) code. The IR code represents the body of a single function.

Implementations

impl<'src> Compiler<'src>

pub fn new(source: &'src [u8]) -> Self

Create a new code generator.

Parameters

• source: The source code.

Returns

The new code generator.

pub fn compile(self, tree: Tree) -> Function

Compile the specified syntax tree into a function in intermediate representation (IR).

Parameters

• tree: The root of the syntax tree.

Returns

The generated code.
