Module Reason_omp.Ast_ioSource

Sourcetype ast =
  1. | Impl : (module Reason_omp__.Migrate_parsetree_versions.OCaml_version with type Ast.Parsetree.structure = 'concrete) * 'concrete -> ast
  2. | Intf : (module Reason_omp__.Migrate_parsetree_versions.OCaml_version with type Ast.Parsetree.signature = 'concrete) * 'concrete -> ast

A marshalled ast packs the ast with the corresponding version of the frontend

Sourcetype filename = string

A simple alias used for the filename of the source that produced an AST

Sourcetype read_error =
  1. | Not_a_binary_ast of string
    (*

    The input doesn't contain a binary AST. The argument corresponds to the bytes from the input that were consumed.

    *)
  2. | Unknown_version of string
    (*

    The input contains a binary AST for an unknown version of OCaml. The argument is the unknown magic number.

    *)

Load a marshalled AST from a channel

Any exception raised during unmarshalling (see Marshal) can escape.

Sourceval from_bytes : bytes -> int -> (filename * ast, read_error) Result.result
