Raised by parsers when the first component of a stream pattern is accepted, but one of the following components is rejected.
val from :
(int -> 'a option) -> 'a t
Stream.from f returns a stream built from the function
To create a new stream element, the function
f is called with
the current stream count. The user function
f must return either
Some <value> for a value or
None to specify the end of the
Do note that the indices passed to
f may not start at
0 in the
general case. For example,
[< '0; '1; Stream.from f >] would call
f the first time with count
val of_list :
'a list -> 'a t
Return the stream holding the elements of the list in the same order.
val of_string :
string -> char t
Return the stream of the characters of the string parameter.
val of_bytes :
bytes -> char t
Return the stream of the characters of the bytes parameter.
val of_channel :
in_channel -> char t
Return the stream of the characters read from the input channel.
val iter :
('a -> unit) -> 'a t -> unit
Stream.iter f s scans the whole stream s, applying function
in turn to each stream element encountered.
val next :
'a t -> 'a
Return the first element of the stream and remove it from the
Stream.Failure if the stream is empty.
val empty :
'a t -> unit
() if the stream is empty, else raise
val peek :
'a t -> 'a option
Some of "the first element" of the stream, or
the stream is empty.
val junk :
'a t -> unit
Remove the first element of the stream, possibly unfreezing it before.
val count :
'a t -> int
Return the current count of the stream elements, i.e. the number of the stream elements discarded.
val npeek :
int -> 'a t -> 'a list
npeek n returns the list of the
n first elements of
the stream, or all its remaining elements if less than
elements are available.
