Predicates[procedure] (byte-blob-stream? X) => BOOL
Returns #t if the given object is a stream that is either empty or its first element is a byte blob, #f otherwise.[procedure] (byte-blob-stream-empty? STREAM) => BOOL
Returns #t if the given stream is empty, #f otherwise.
Constructors[procedure] (byte-blob-stream-empty) => STREAM
Returns an empty stream.[procedure] (byte-blob-stream-cons BYTE-BLOB STREAM) => STREAM
Prepends the given byte blob to the given stream and returns the resulting stream.
Accessors[procedure] (byte-blob-stream-length STREAM) => INTEGER
Returns the number of elements contained in all byte blobs in the given stream.[procedure] (byte-blob-stream-car STREAM) => X
Returns the first element of the first byte blob contained in the given stream. The stream argument must be non-empty, or an exception will be thrown.[procedure] (byte-blob-stream-cdr STREAM) => STREAM
Returns a stream that contains the elements after the first element of the given byte blob. The argument stream must be non-empty, or an exception will be thrown.[procedure] (byte-blob-stream-ref STREAM I) => BYTE
Returns the i-th element of the given stream of byte blobs.
Transformers[procedure] (byte-blob-stream-append STREAM STREAM) => STREAM
Appends two streams of byte blobs together.[procedure] (byte-blob-stream-reverse STREAM) => STREAM
Returns a stream that contains the elements of the given stream of byte blobs in reverse order.[procedure] (byte-blob-stream-intersperse STREAM BYTE) => STREAM
Returns a stream of byte blobs with the given byte placed between the elements of the each byte blob from the input stream, and between byte blobs.[procedure] (byte-blob-stream-map F STREAM) => STREAM
Returns a stream of byte blobs obtained by applying F to each element of the byte blobs in the input stream.[procedure] (byte-blob-stream->list STREAM) => LIST
Returns a list containing the elements of the byte blobs contained in the input stream. If procedure F is provided as a second argument, it is applied to every element of the returned list.
Subsequences[procedure] (byte-blob-stream-take STREAM N) => STREAM
Returns the prefix of the given stream of byte blobs of length N.[procedure] (byte-blob-stream-drop STREAM N) => STREAM
Returns the suffix of the given stream of byte blobs after the first N elements.[procedure] (byte-blob-stream-span STREAM START END) => STREAM
Returns the subsequence of the given stream of byte blobs from position START to position END.
Fold[procedure] (byte-blob-stream-fold-left F INIT STREAM) => VALUE
[procedure] (byte-blob-stream-fold-right F INIT STREAM) => VALUE
Given a procedure of two arguments, a starting value, and a stream of byte blobs, reduces the stream using the supplied procedure, from left to right, or right to left, respectively.
Find[procedure] (byte-blob-stream-find NEEDLE HAYSTACK) => LIST
Finds all non-overlapping instances of the byte blob NEEDLE in the stream of byte blobs HAYSTACK. The first element of the returned list is the prefix of HAYSTACK prior to any matches of NEEDLE. The second is a list of lists.
The first element of each pair in the list is a span from the beginning of a match to the beginning of the next match, while the second is a span from the beginning of the match to the end of the input.
Files[procedure] (file->byte-blob-stream FILENAME [BLOCKSIZE] ) => STREAM
Reads a file into a byte-blob stream.
- 1.3 Added optional second argument to byte-blob-stream->list
- 1.2 Added procedure file->byte-blob-stream
- 1.0 Initial release
Based on ideas from the Haskell bytestring library.
The code for byte-blob-stream-find is based on code from the Haskell Text library by Tom Harper and Bryan O'Sullivan.
