Trait AsErrTree

pub trait AsErrTree {
    // Required method
    fn as_err_tree(&self, func: &mut dyn FnMut(ErrTree<'_>));
}

Defines an Error’s temporary view as an ErrTree for printing.

This can be defined with err_tree, manually (see ErrTree), or with the default dyn implementation. The dyn implementation does not track any more information than standard library errors or track multiple sources.

Implementors must call func with a properly constructed ErrTree.

Required Methods

fn as_err_tree(&self, func: &mut dyn FnMut(ErrTree<'_>))

Constructs the ErrTree internally and calls func on it.

Implementations on Foreign Types

impl AsErrTree for Error

Available on crate feature anyhow only.

impl AsErrTree for dyn Error

Displays with Error::source as the child.

Does not provide any of the extra tracking information or handle multiple sources.
