Struct Frame 

pub struct Frame { /* private fields */ }

A frame in the exception tree.

Implementations

impl Frame

pub fn error(&self) -> &(dyn Error + Send + Sync + 'static)

Return the error as a reference to Error.

pub fn location(&self) -> &'static Location<'static>

Return the source code location where this exception frame was created.

pub fn children(&self) -> &[Frame]

Return a slice of the children of the exception.

impl Frame

Navigation

pub fn probable_cause(&self) -> Option<&Frame>

Find the best possible cause:

• in a linear chain of a single error each, it’s the last-most child frame
• in trees, find the deepest-possible frame that has the most leafs as children

Return None if there are no children.

pub fn iter_frames(&self) -> impl Iterator<Item = &Frame> + '_

Iterate over all frames in breadth-first order. The first frame is this instance, followed by all of its children.
