What is wrong with a declaration.

Variants (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.

MissingDb

The router holds no toasty::Db.

MissingAuthModels

Auth is on, but the Db does not register the shipped models it needs.

Fields

models: Vec<&'static str>

The unregistered models.

ShellAssetsWithoutBundle

Panel::shell_assets is set, but the router has no asset bundle.

InvalidSegment

A path segment the panel routes cannot be a literal URL segment.

Fields

item: &'static str

What names the segment: panel prefix, ResourceDef::slug or Page::slug.

segment: String

The refused segment.

fault: SegmentFault

Why it is refused.

PrefixOverlapsRuntime

The prefix overlaps Topcoat’s runtime endpoints.

Fields

prefix: String

The panel’s prefix.

PrefixOverlapsPanel

The prefix overlaps another panel’s.

Fields

other: String

The other panel’s prefix.

ServeDirWithoutCatchAll

A Panel::serve_dir pattern that does not end in a catch-all.

Fields

path: String

The pattern.

ServeDirTwice

The panel serves the same directory pattern twice.

Fields

path: String

The pattern.

ServeDirTaken

Another panel already serves the directory pattern.

Fields

path: String

The pattern.

panel: String

The serving panel’s prefix.

SecondHome

A second Panel::home page.

DuplicateResource

The resource is registered on the panel twice.

NotMounted

The resource is not mounted on the request’s panel.

ReservedSlug

A slug naming a route the panel serves itself.

Fields

slug: String

The slug.

DuplicateSlug

A slug another resource or page already mounts at.

Fields

slug: String

The slug.

DuplicateAction

Two actions share a NAME.

Fields

name: &'static str

The shared name.

DuplicateRelation

Two relations to the same resource.

UnregisteredRelation

A relation to a resource the panel does not register.

UnregisteredOptionSource

A relationship field whose options come from a resource the panel does not register.

Fields

field: String

The field.

source: &'static str

The option source’s type.

TraversalLens

A lens with more than one step where a single field of the model is needed.

Fields

steps: usize

The lens’s step count.

UnresolvedLens

A multi-step lens that resolves to no single column.

Fields

model: &'static str

The lens’s model.

steps: Vec<usize>

The lens’s field indices, step by step.

TenancyColumnNotAField

A Tenancy::column lens that names no field of the model.

TenancyViaOwnColumn

A Tenancy::via lens that names one field of the model.

TenancyViaWithoutBelongsTo

A Tenancy::via lens whose first step is no belongs_to relation.

UnguardedForeignKey

A Tenancy::via resource whose form writes the parent’s foreign key other than through a relationship field over a tenant-scoped resource of the parent’s model.

Fields

relation: String

The belongs_to relation the lens steps through.

keys: Vec<String>

The foreign-key columns written another way.

NoColumns

A table with no column.

ZeroPageSize

Table::paginate(0).

DuplicateColumn

Two table columns share a name.

Fields

name: String

The shared name.

DuplicateFilter

Two table filters share a name.

Fields

name: String

The shared name.

DuplicateField

Two schema fields share a name.

Fields

name: String

The shared name.

EmptyFormOverride

A form() override that declares no control over a record form with fields.

FormWithoutRecordForm

A form schema on a resource whose Form serves no form.

CreateWithoutForm

A resource whose policy allows create but that has no form.

UnboundControl

A form control no record-form field binds, so its input is never written.

Fields

control: String

The control’s key.

ControlBoundTwice

A form control more than one record-form field binds.

Fields

control: String

The control’s key.

MissingControl

A record-form field binding a key the form declares no control for.

Fields

field: String

The field.
