Module Devkit_core.ControlSource

Control flow

Sourceval bracket : 'a -> ('a -> unit) -> ('a -> 'b) -> 'b

bracket resource destroy k

  • returns

    k resource and guarantee that resource is destroy'ed at the end.

Sourceval wrapped : 'a -> ('a -> 'b) -> ('a -> unit) -> 'b

wrapped acc result k

Computation k accumulates result into resource acc which is guaranteed to be released at the end. Rarely useful (e.g. IO.output_string)

  • returns

    result acc
