Struct BreakpointEdit 

pub struct BreakpointEdit<'a> { /* private fields */ }

A breakpoint-editing session.

This enables updating breakpoint state (setting or unsetting individual breakpoints or the store-global single-step flag) in a batch. It is more efficient to batch these updates because “re-publishing” the newly patched code, with update breakpoint settings, typically requires a syscall to re-enable execute permissions.

Implementations

impl<'a> BreakpointEdit<'a>

pub fn add_breakpoint(&mut self, module: &Module, pc: u32) -> Result<(), Error>

Add a breakpoint in the given module at the given PC in that module.

No effect if the breakpoint is already set.

pub fn remove_breakpoint( &mut self, module: &Module, pc: u32, ) -> Result<(), Error>

Remove a breakpoint in the given module at the given PC in that module.

No effect if the breakpoint was not set.

pub fn single_step(&mut self, enabled: bool) -> Result<(), Error>

Turn on or off single-step mode.

In single-step mode, a breakpoint event is emitted at every Wasm PC.

Trait Implementations

impl<'a> Drop for BreakpointEdit<'a>

fn drop(&mut self)

Executes the destructor for this type.
