Enum Interceptor 

pub enum Interceptor {
    None,
    Debugger(DebuggerCommand),
    Tracer(TracerCommand),
}

An interceptor wraps test execution with a debugger or tracer.

Variants

None

No interceptor - standard test execution.

Debugger(DebuggerCommand)

Run the test under a debugger.

Tracer(TracerCommand)

Run the test under a syscall tracer.

Implementations

impl Interceptor

pub fn should_disable_timeouts(&self) -> bool

Returns true if timeouts should be disabled.

Both debuggers and tracers disable timeouts.

pub fn should_passthrough_stdin(&self) -> bool

Returns true if stdin should be passed through to child test processes.

Only debuggers need stdin passthrough for interactive debugging.

pub fn should_create_process_group(&self) -> bool

Returns true if a process group should be created for the child.

Debuggers need terminal control, so no process group is created. Tracers work fine with process groups.

pub fn should_skip_leak_detection(&self) -> bool

Returns true if leak detection should be skipped.

Both debuggers and tracers skip leak detection to avoid interference.

pub fn should_show_wrapper_command(&self) -> bool

Returns true if the test command should be displayed.

Used to determine if we should print the wrapper command for debugging.

pub fn should_send_sigtstp(&self) -> bool

Returns true if, on receiving SIGTSTP, we should send SIGTSTP to the child.

Debugger mode has special signal handling where we don’t send SIGTSTP to the child (it receives it directly from the terminal, since no process group is created). Tracers use standard signal handling.

Trait Implementations

impl Clone for Interceptor

fn clone(&self) -> Interceptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Interceptor

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

Formats the value using the given formatter.

impl Default for Interceptor

fn default() -> Interceptor

Returns the “default value” for a type.
