Struct datafusion_jit::api::Assembler

pub struct Assembler { /* private fields */ }

The very first step for constructing a function at runtime.

Implementations

impl Assembler

pub fn register_extern_fn( &self, name: impl Into<String>, ptr: *const u8, params: Vec<JITType>, returns: Option<JITType> ) -> Result<()>

Register an external Rust function to make it accessible by runtime generated functions. Parameters and return types are used to impose type safety while constructing an AST.

pub fn new_func_builder(&self, name: impl Into<String>) -> FunctionBuilder

Create a new FunctionBuilder with name prefix

pub fn create_jit(&self) -> JIT

Create JIT env which we could compile the AST of constructed function into runnable code.

Trait Implementations

impl Default for Assembler

fn default() -> Self

Returns the “default value” for a type.
