Enum midenc_codegen_masm::Breakpoint

pub enum Breakpoint {
    All,
    Cycle(usize),
    At(InstructionPointer),
    Loops,
    Called(FunctionIdent),
    Watch(WatchpointId),
}

A breakpoint can be used to force the emulator to suspend execution when a specific event or condition is reached.

When hit, control is handed back to the owner of the emulator so that they can inspect the state, potentially make changes, and then resume execution if desired.

Variants

All

Break after each cycle

Cycle(usize)

Break when the cycle count reaches N

At(InstructionPointer)

Step until control reaches the given instruction pointer value

Loops

Break at loop instructions

The break will start on the looping instruction itself, and when execution resumes, will break either at the next nested loop, or if a complete iteration is reached, one of two places depending on the type of looping instruction we’re in:

• while.true will break at the while.true on each iteration
• repeat.n will break at the top of the loop body on each iteration

Called(FunctionIdent)

Break when the given function is called

Watch(WatchpointId)

Break when the given watchpoint is hit

This is also referred to as a watchpoint

Trait Implementations

impl Clone for Breakpoint

fn clone(&self) -> Breakpoint

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Breakpoint

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

Formats the value using the given formatter.

impl PartialEq for Breakpoint

fn eq(&self, other: &Breakpoint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
