Struct Assembler 

pub struct Assembler { /* private fields */ }

Assembles a series of RawOp into raw bytes, tracking and resolving macros and labels, and handling dynamic pushes.

Example

use etk_asm::asm::Assembler;
use etk_asm::ops::AbstractOp;
use etk_ops::shanghai::{Op, GetPc};
let mut asm = Assembler::new();
asm.push_all(vec![
    AbstractOp::new(GetPc),
])?;
let output = asm.take();
asm.finish()?;

Implementations

impl Assembler

pub fn new() -> Self

Create a new Assembler.

pub fn finish(self) -> Result<(), Error>

Indicate that the input sequence is complete. Returns any errors that may remain.

pub fn take(&mut self) -> Vec<u8>

Collect any assembled instructions that are ready to be output.

pub fn push_all<I, O>(&mut self, ops: I) -> Result<usize, Error>

where I: IntoIterator<Item = O>, O: Into<RawOp>,

Feed instructions into the Assembler.

Returns the number of bytes that can be collected with Assembler::take.

pub fn push<O>(&mut self, rop: O) -> Result<usize, Error>

where O: Into<RawOp>,

Feed a single instruction into the Assembler.

Returns the number of bytes that can be collected with Assembler::take

Trait Implementations

impl Debug for Assembler

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Assembler

fn default() -> Self

Returns the “default value” for a type.
