}

Common breakpoints.

Variants

PC(u16)

Break when the PC is equal to the given value.

Reg

Break when the provided register is set to a given value.

Fields

reg: Reg

Register to check.

value: Comparator

Predicate to break against.

Mem

Break when the provided memory address is written to with a given value.

Fields

addr: u16

Address to check.

value: Comparator

Predicate to break against.

Generic(Box<dyn Fn(&Simulator) -> bool + Send + Sync + 'static>)

Breaks based on an arbitrarily defined function.

This can be constructed with the Breakpoint::generic function.

And(Box<[Breakpoint]>)

All conditions have to apply for the break to be applied.

Or(Box<[Breakpoint]>)

One of these conditions have to apply for the break to be applied.

Implementations

impl Breakpoint

pub fn generic( f: impl Fn(&Simulator) -> bool + Send + Sync + 'static ) -> Breakpoint

Creates a breakpoint out of a function.

pub fn check(&self, sim: &Simulator) -> bool

Checks if a break should occur.

Trait Implementations

impl BitAnd for Breakpoint

type Output = Breakpoint

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self::Output

Performs the & operation.

impl BitOr for Breakpoint

type Output = Breakpoint

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

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: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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