Struct zircon_object::task::ExceptionObject
source · [−]pub struct ExceptionObject { /* private fields */ }
Expand description
The exception object received from the exception channel.
This will be transmitted to registered exception handlers in userspace and provides them with exception state and control functionality. We do not send exception directly since it’s hard to figure out when will the handle close.
Implementations
sourceimpl ExceptionObject
impl ExceptionObject
sourcepub fn get_thread_handle(&self) -> Handle
pub fn get_thread_handle(&self) -> Handle
Create a handle for the exception’s thread.
sourcepub fn get_process_handle(&self) -> ZxResult<Handle>
pub fn get_process_handle(&self) -> ZxResult<Handle>
Create a handle for the exception’s process.
sourcepub fn state(&self) -> u32
pub fn state(&self) -> u32
Get whether closing the exception handle will finish exception processing and resume the underlying thread.
sourcepub fn set_state(&self, state: u32) -> ZxResult
pub fn set_state(&self, state: u32) -> ZxResult
Set whether closing the exception handle will finish exception processing and resume the underlying thread.
sourcepub fn strategy(&self) -> u32
pub fn strategy(&self) -> u32
Get whether the debugger gets a ‘second chance’ at handling the exception if the process-level handler fails to do so.
sourcepub fn set_strategy(&self, strategy: u32) -> ZxResult
pub fn set_strategy(&self, strategy: u32) -> ZxResult
Set whether the debugger gets a ‘second chance’ at handling the exception if the process-level handler fails to do so.
