Module Iobuf.PeekSource

Peek and Poke functions access a value at pos from the lower bound of the window and do not advance.

Peek.bin_prot X.bin_read_t t returns the initial X.t in t without advancing.

Following the bin_prot protocol, the representation of x is X.bin_size_t x bytes long. Peek., Poke., Consume., and Fill.bin_prot do not add any size prefix or other framing to the bin_prot representation.

Sourcetype 'seek src = (Core.read, 'seek) t

Similar to Consume.To_*, but do not advance the buffer.

Sourceval index : ([> Core.read ], _) iobuf -> ?pos:int -> ?len:int -> char -> int option

index ?pos ?len t c returns Some i for the smallest i >= pos such that char t i = c, or None if there is no such i.

  • parameter pos

    default = 0

  • parameter len

    default = length t - pos
