Struct PackingError 

pub struct PackingError { /* private fields */ }

A packing could not be found that satisfied all offsets

If the “dot2” feature is enabled, you can use the write_graph_viz method on this error to dump a text representation of the graph to disk. You can then use graphviz to convert this into an image. For example, to create an SVG, you might use, dot -v -Tsvg failure.dot2 > failure.svg, where ‘failure.dot2’ is the path where you dumped the graph.

Implementations

impl PackingError

pub fn write_graph_viz(&self, path: impl AsRef<Path>) -> Result<()>

Available on crate feature dot2 only.

Write a graphviz file representing the failed packing to the provided path.

Has the same semantics as std::fs::write.

Trait Implementations

impl Clone for PackingError

fn clone(&self) -> PackingError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PackingError

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

Formats the value using the given formatter.

impl Display for PackingError

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

Formats the value using the given formatter.

impl Error for PackingError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
