Overview

Package adapter_3_16 provides conversion functions between core types and protocol_3_16 types. Core types use UTF-8 byte offsets for natural Go string handling, while protocol types use UTF-16 code unit offsets as specified by the LSP specification.

LSP 3.16 Specification: https://microsoft.github.io/language-server-protocol/specifications/lsp/3.16/specification/

These adapters handle the critical conversion at API boundaries: - Convert core types (UTF-8 offsets) to protocol types (UTF-16 code units) when sending to clients - Convert protocol types (UTF-16 code units) to core types (UTF-8 offsets) when receiving from clients
