12.10 Fast-Load Serialization
The bindings documented in this section are provided by the racket/fasl library, not racket/base or racket.
procedure
(s-exp->fasl v [out]) → (or/c (void) bytes?)
v : any/c out : (or/c output-port? #f) = #f
procedure
(fasl->s-exp in) → any/c
in : (or/c input-port? bytes?)
The s-exp->fasl function serializes v to a byte
string, printing it directly to out if out is an
output port or return the byte string otherwise. The
fasl->s-exp function decodes a value from a byte string
(supplied either directly or as an input port) that was encoded with
s-exp->fasl.
The v argument must be a value that could be quoted as a literal, because s-exp->fasl essentially uses (compile `',v) to encode the value using Racket’s built-in fast-load format for bytecode.
The byte-string encoding produced by s-exp->fasl is specific to a version of Racket. That is, the resulting byte string can be decoded back to v only using the same version with which it was encoded.
