module Prism::Relocation - prism: Ruby Standard Library Documentation

# module Prism::Relocation

`Prism` parses deterministically for the same input. This provides a nice property that is exposed through the node_id API on nodes. Effectively this means that for the same input, these values will remain consistent every time the source is parsed. This means we can reparse the source same with a node_id value and find the exact same node again.

The `Relocation` module provides an API around this property. It allows you to “save” nodes and locations using a minimal amount of memory (just the node_id and a field identifier) and then reify them later.
