SYNOPSIS

          typedef enum {
             BSON_VALIDATE_NONE = 0,
             BSON_VALIDATE_UTF8 = (1 << 0),
             BSON_VALIDATE_DOLLAR_KEYS = (1 << 1),
             BSON_VALIDATE_DOT_KEYS = (1 << 2),
             BSON_VALIDATE_UTF8_ALLOW_NULL = (1 << 3),
             BSON_VALIDATE_EMPTY_KEYS = (1 << 4),
          } bson_validate_flags_t;

          bool
          bson_validate_with_error (const bson_t *bson,
                                    bson_validate_flags_t flags,
                                    bson_error_t *error);

PARAMETERS

       • bson: A bson_t.

       • flags: A bitwise-or of all desired validation flags.

       • error: Optional bson_error_t.

DESCRIPTION

       Validates  a  BSON  document by walking through the document and inspecting the keys and values for valid
       content.

       You can modify how the validation occurs through the use of the flags parameter. A description  of  their
       effect is below.

       • BSON_VALIDATE_NONE Basic validation of BSON length and structure.

       • BSON_VALIDATE_UTF8 All keys and string values are checked for invalid UTF-8.

       • BSON_VALIDATE_UTF8_ALLOW_NULL String values are allowed to have embedded NULL bytes.

       • BSON_VALIDATE_DOLLAR_KEYS Prohibit keys that start with $ outside of a "DBRef" subdocument.

       • BSON_VALIDATE_DOT_KEYS Prohibit keys that contain . anywhere in the string.

       • BSON_VALIDATE_EMPTY_KEYS Prohibit zero-length keys.

RETURNS

       Returns true if bson is valid; otherwise false and error is filled out.

       The bson_error_t domain is set to BSON_ERROR_INVALID. Its code is set to one of the bson_validate_flags_t
       flags indicating which validation failed; for example, if a key contains invalid UTF-8, then the code  is
       set to BSON_VALIDATE_UTF8, but if the basic structure of the BSON document is corrupt, the code is set to
       BSON_VALIDATE_NONE. The error message is filled out, and gives more detail if possible.

          bson_validate().

          bson_visitor_t can be used for custom validation, Example Custom Validation.
