Expand description

Why a route could not be used.

Variants§

§

IndexCount

The route wants a different number of indices than it was given.

Fields

§route: String

The route.

§wanted: usize

How many Element steps it has.

§given: usize

How many indices arrived.

§

NoSuchField

The schema has no such field at that point in the route.

Fields

§route: String

The route.

§label: String

The label that was not found.

§at: String

How far the walk got.

§

NotAList

The route indexes something that is not a list.

Fields

§route: String

The route.

§at: String

How far the walk got.

§

NotAStruct

The route descends into something with no fields under it.

Fields

§route: String

The route.

§at: String

How far the walk got.

§

NamesNoField

The route ends without naming a field.

An empty route, or one ending at a list element rather than at something the element holds.

Fields

§route: String

The route.

§

AmbiguousArm

The label is declared more than once at that point, so no single entry describes it.

Not a defect on its own. Both arms of a split may declare a label with different write rules, and which applies depends on the selector’s value in one file. The address is the same either way, so a caller that wants the location rather than the entry uses FieldRoute::entries_in and gets both.

Fields

§count: usize

How many entries declare it.

§route: String

The route.

§label: String

The label declared twice.

§at: String

How far the walk got.
