package base_bigstring

Release v0.17.0

• Removed parameters and attributes:

  • Removed max_mem_waiting_gc_in_bytes parameter from Base_bigstring.create

• Added functions:

  • Base_bigstring.unsafe_memset for filling a range with a character without bounds checks
  • Base_bigstring.memcmp_string for efficient comparison between Bigstring and string data
  • Base_bigstring.get_string and Base_bigstring.unsafe_get_string (also in Base_bigstring.Local) for obtaining strings with specified position and length, avoiding optional arguments

• Improved performance of accessors which convert a 64-bit integer to an int:

  • Base_bigstring.get_int64_le_exn
  • Base_bigstring.get_int64_be_exn
  • Base_bigstring.get_uint64_le_exn
  • Base_bigstring.get_uint64_be_exn
  • Base_bigstring.unsafe_get_int64_le_exn
  • Base_bigstring.unsafe_get_int64_be_exn
  • Base_bigstring.unsafe_get_uint64_le_exn
  • Base_bigstring.unsafe_get_uint64_be_exn

Release v0.16.0:

• Improved support for locals (stack allocation):

  • Add [@local] attribute to the t arguments of length, unsafe_set_int8, unsafe_set_int16_le, unsafe_set_int16_be, unsafe_set_int32_le and unsafe_set_int32_be.
  • Likewise for the Int64.t arguments of set_int64_t_le, set_int64_t_be, unsafe_set_int64_t_le, and unsafe_set_int64_t_be.
  • Add new Local module providing get_int64_t_le, get_int64_t_be, unsafe_get_int64_t_le, and unsafe_get_int64_t_be functions that return local Int64.t values.

• New functions:

  • unsafe_get: retrieves character at specified position, without bounds checks
  • unsafe_set: sets character at specified position, without bounds checks
  • memmem: searches for the position of a substring of needle in a substring of haystack with optional parameters for positions and lengths; returns an int option
  • unsafe_memmem: unsafe version of memmem function, without bounds checks
