Smart-buffer provides an output buffer which changes the destination depending on content size.
* In-memory buffer for small data
* Temporary files on disk for big data
In-memory buffer is fast to read/write, however, it consumes much memory if the data can be large. On the other hand, files on disk are slower. Smart-buffer would be useful when the buffer must satisfy these two contradicting demands.
## Usage
‘with-smart-buffer‘ returns an in-memory stream or a file stream.
“‘common-lisp
(with-smart-buffer (buffer)
(write-to-buffer buffer (flex:string-to-octets "foobar")))
;=> #<FLEXI-STREAMS::VECTOR-INPUT-STREAM {100456A9A3}>
(with-smart-buffer (buffer :memory-limit 3)
(write-to-buffer buffer (flex:string-to-octets "foobar")))
;=> #<SB-SYS:FD-STREAM for "file /private/var/folders/x3/8n07clk15tq3m4y6_yrmjy6c0000gn/T/tmpAR3FSGEY.tmp" {1005D06503}>
