// Written in the D programming language.
/**
*
D constrains integral types to specific sizes. But efficiency
of different sizes varies from machine to machine,
pointer sizes vary, and the maximum integer size varies.
<b>stdint</b> offers a portable way of trading off size
vs efficiency, in a manner compatible with the <tt>stdint.h</tt>
definitions in C.
The exact aliases are types of exactly the specified number of bits.
The at least aliases are at least the specified number of bits
large, and can be larger.
The fast aliases are the fastest integral type supported by the
processor that is at least as wide as the specified number of bits.
The aliases are:
$(ATABLE $(TR
$(TH Exact Alias)
$(TH Description)
$(TH At Least Alias)
$(TH Description)
$(TH Fast Alias)
$(TH Description)
)$(TR
$(TD int8_t)
$(TD exactly 8 bits signed)
$(TD int_least8_t)
$(TD at least 8 bits signed)
$(TD int_fast8_t)

$(TD uint_least64_t)
$(TD at least 64 bits unsigned)
$(TD uint_fast64_t)

))
The ptr aliases are integral types guaranteed to be large enough
to hold a pointer without losing bits:
$(ATABLE $(TR
$(TH Alias)
$(TH Description)
)$(TR
$(TD intptr_t)
$(TD signed integral type large enough to hold a pointer)
)$(TR
$(TD uintptr_t)
$(TD unsigned integral type large enough to hold a pointer)
))
The max aliases are the largest integral types:
$(ATABLE $(TR
$(TH Alias)
$(TH Description)
)$(TR
$(TD intmax_t)
$(TD the largest signed integral type)
)$(TR
$(TD uintmax_t)
$(TD the largest unsigned integral type)
))
