All
programs
have
to
manage
the
way
they
use
a
computer's
memory
while
running.
Some
languages
have
garbage
collection
that
constantly
looks
for
no
longer
used
memory
as
the
program
runs;
in
other
languages,
the
programmer
must
explicitly
allocate
and
free
the
memory.
Rust
uses
a
third
approach:
memory
is
managed
through
a
system
of
ownership
with
a
set
of
rules
that
the
compiler
checks
at
compile
time.
None
of
the
ownership
features
slow
down
your
program
while
it's
running.
