const { SeekerSync } = Deno;
An abstract interface which when implemented provides an interface to seek within an open file/resource synchronously.
Methods
seekSync(offset: number, whence: SeekMode): number
Seek sets the offset for the next readSync() or writeSync() to
offset, interpreted according to whence: Start means relative
to the start of the file, Current means relative to the current
offset, and End means relative to the end.
Seeking to an offset before the start of the file is an error. Seeking to any positive offset is legal, but the behavior of subsequent I/O operations on the underlying object is implementation-dependent.
It returns the updated offset.
