Struct comfy_wgpu::backtrace::Frame
pub struct Frame { /* private fields */ }Expand description
A trait representing one frame of a backtrace, yielded to the trace
function of this crate.
The tracing function’s closure will be yielded frames, and the frame is virtually dispatched as the underlying implementation is not always known until runtime.
Implementations§
§impl Frame
impl Frame
pub fn ip(&self) -> *mut c_void
pub fn ip(&self) -> *mut c_void
Returns the current instruction pointer of this frame.
This is normally the next instruction to execute in the frame, but not all implementations list this with 100% accuracy (but it’s generally pretty close).
It is recommended to pass this value to backtrace::resolve to turn it
into a symbol name.
pub fn sp(&self) -> *mut c_void
pub fn sp(&self) -> *mut c_void
Returns the current stack pointer of this frame.
In the case that a backend cannot recover the stack pointer for this frame, a null pointer is returned.
pub fn symbol_address(&self) -> *mut c_void
pub fn symbol_address(&self) -> *mut c_void
Returns the starting symbol address of the frame of this function.
This will attempt to rewind the instruction pointer returned by ip to
the start of the function, returning that value. In some cases, however,
backends will just return ip from this function.
The returned value can sometimes be used if backtrace::resolve failed
on the ip given above.
pub fn module_base_address(&self) -> Option<*mut c_void>
pub fn module_base_address(&self) -> Option<*mut c_void>
Returns the base address of the module to which the frame belongs.
