Shape descriptor is a format to describe data. This format optimizes for fast detection of value present given a shape and a value path.

This namespace contains functions to operate on maps in the shape descriptor format.

data->shape-descriptorclj/s

(data->shape-descriptor data)

Helper function to transform a map into an shape descriptor.

Edges of shape descriptor are always an empty map. If a value of the map is a sequence. This will combine the keys present in all items on the final shape description.

WARN: this idea of merging is still under test, this may change in the future.

missingclj/s

(missing available-shape required-shape)
(missing available required data)

Given some available and required shapes, returns which items are missing from available in the required. Returns nil when nothing is missing.

missing-from-dataclj/s

(missing-from-data available-data required-shape)

Like missing, but starts from data instead of shape. If you are starting from data prefer this over missing, this can perform better by avoiding scanning the whole available data to build a shape, when the required-shape is a sub-set of the available data.

relax-empty-collectionsclj/s

(relax-empty-collections required data)

This helper will remove nested requirements when data is an empty collection. This allows for nested inputs with empty collections to still be valid in shape.
