Struct dynasmrt::SimpleAssembler

pub struct SimpleAssembler {
    pub ops: Vec<u8>,
}

An assembler that is purely a Vec<u8>. It doesn't support labels or architecture-specific directives, but can be used to easily inspect generated code. It is intended to be used in testcases.

Fields

ops: Vec<u8>

The assembling buffer.

Implementations

impl SimpleAssembler

pub fn new() -> SimpleAssembler

Creates a new SimpleAssembler, containing an empty Vec.

pub fn alter(&mut self) -> UncommittedModifier<'_>

Use an UncommittedModifier to alter uncommitted code.

pub fn finalize(self) -> Vec<u8>

Destroys this assembler, returning the Vec<u8> contained within
