Struct npyz::write_options::WriteOptions

pub struct WriteOptions<T: ?Sized> { /* fields omitted */ }

Represents an almost-empty configuration for an NpyWriter.

Construction of an NpyWriter always begins here, with a call to WriteOptions::new. Then the methods of the WriterBuilder trait must be used to supply options. See that trait for more details.
