A slice
is a part of a binary representation of some data. The concatenation of multiple slice represents the whole data.
val make_slicer_state :
string ->
offset:int ->
length:int ->
slicer_state option
None
if offset
and length
do not describe a valid substring.
val slice :
_ Encoding.t ->
slicer_state ->
(slice list, Data_encoding__.Binary_error_types.read_error) result
slice e b offset length
slices the data represented by the length
bytes in b
starting at index offset
.
If e
does not correctly describe the given bytes (i.e., if read
would fail on equivalent parameters) then it returns Error
.
val slice_opt : _ Encoding.t -> slicer_state -> slice list option
val slice_exn : _ Encoding.t -> slicer_state -> slice list
val slice_string : _ Encoding.t -> string -> (slice list, read_error) result
slice_string
slices the whole content of the buffer.
