Potential errors when adding to a PolicySet.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

AlreadyDefined(AlreadyDefined)

There was a duplicate PolicyId encountered in either the set of templates or the set of policies.

§

Linking(LinkingError)

Error when linking a template

§

ExpectedStatic(ExpectedStatic)

Expected a static policy, but a template-linked policy was provided

§

ExpectedTemplate(ExpectedTemplate)

Expected a template, but a static policy was provided.

§

PolicyNonexistent(PolicyNonexistentError)

Error when removing a static policy that doesn’t exist

§

TemplateNonexistent(TemplateNonexistentError)

Error when removing a template that doesn’t exist

Error when removing a template with active links

§

RemoveTemplateNotTemplate(RemoveTemplateNotTemplateError)

Error when removing a template that is not a template

§

LinkNonexistent(LinkNonexistentError)

Error when unlinking a linked policy

Error when removing a link that is not a link

§

FromJson(PolicyFromJsonError)

Error when converting a policy/template from JSON format

§

ToJson(PolicyToJsonError)

Error when converting a policy/template to JSON format

§

JsonPolicySet(JsonPolicySetError)

Error during JSON ser/de of the policy set (as opposed to individual policies)

Trait Implementations§

impl Debug for PolicySetError

source§

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

Formats the value using the given formatter. Read more
source§

impl Diagnostic for PolicySetError

source§

fn code(&self) -> Option<Box<dyn Display + '_>>

Unique diagnostic code that can be used to look up more information about this Diagnostic. Ideally also globally unique, and documented in the toplevel crate’s documentation for easy searching. Rust path format (foo::bar::baz) is recommended, but more classic codes like E0123 or enums will work just fine.

fn help(&self) -> Option<Box<dyn Display + '_>>

Additional help text related to this Diagnostic. Do you have any advice for the poor soul who’s just run into this issue?
source§

fn severity(&self) -> Option<Severity>

Diagnostic severity. This may be used by ReportHandlers to change the display format of this diagnostic. Read more
