Module Packed_float_option.Ref

For records not consisting purely of floats, fields of t are preferable to mutable fields of Packed_float_option.t because their value can be mutated without crossing the GC write barrier.

This is because float storage in a record of mixed types must be boxed, so changing a mutable Packed_float_option.t requires a caml_modify call to point the mutable field to a different float. In contrast, a t stores an unboxed float which may be modified directly.

type t
include Core.Bin_prot.Binable.S with type t := t
include Bin_prot.Binable.S_only_functions with type t := t
include sig ... end
val bin_size_t : t Bin_prot.Size.sizer
val bin_write_t : t Bin_prot.Write.writer
val bin_read_t : t Bin_prot.Read.reader
val __bin_read_t__ : t Bin_prot.Read.vtag_reader

This function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.
