Module Iobuf.Blit

Blit copies between iobufs and advances neither src nor dst.

type 'rw t_no_seek = ('rw, no_seek) t
include Core__.Import.Blit.S_permissions with type 'rw t := 'rw t_no_seek
type -'perms t
val blit : ([> Core_kernel.Perms.Export.read ] t, [> Core_kernel.Perms.Export.write ] t) Base.Blit.blit
val blito : ([> Core_kernel.Perms.Export.read ] t, [> Core_kernel.Perms.Export.write ] t) Base.Blit.blito
val unsafe_blit : ([> Core_kernel.Perms.Export.read ] t, [> Core_kernel.Perms.Export.write ] t) Base.Blit.blit
val sub : ([> Core_kernel.Perms.Export.read ] t, [< _ Core_kernel.Perms.Export.perms ] t) Base.Blit.sub
val subo : ([> Core_kernel.Perms.Export.read ] t, [< _ Core_kernel.Perms.Export.perms ] t) Base.Blit.subo
val sub : ([> Core__.Import.read ], no_seek) t -> pos:int -> len:int -> (_, _) t

Override types of sub and subo to allow return type to have seek as needed.

val subo : ?⁠pos:int -> ?⁠len:int -> ([> Core__.Import.read ], no_seek) t -> (_, _) t
val blit_maximal : src:[> Core__.Import.read ] t_no_seek -> ?⁠src_pos:int -> dst:[> Core__.Import.write ] t_no_seek -> ?⁠dst_pos:int -> unit -> int

Copies as much as possible (returning the number of bytes copied) without running out of either buffer's window.
