       3
       +
           This library provides a type-safe way to chain JMAP method calls

     

       4
       +
           with automatic response deserialization. Inspired by Ctypes, it uses

     

       5
       +
           GADTs to track method signatures and response types at compile time.

       +
           

     

       7
       +
           The design separates method definition from execution, allowing for

     

       8
       +
           flexible composition while maintaining type safety.

       This package provides standard module type signatures for JMAP (RFC 8620/8621)

     

       6
       +
       implementations in OCaml. It defines consistent interfaces for JSON serialization,

       pretty-printing with Fmt, RFC compliance tracking, and JMAP-specific patterns

       like method arguments/responses and patchable objects.

     

       9

       10

       These signatures ensure consistency across JMAP libraries and make it easy to
