Struct VortexSession 

pub struct VortexSession(/* private fields */);

A Vortex session encapsulates the set of extensible arrays, layouts, compute functions, dtypes, etc. that are available for use in a given context.

It is also the entry-point passed to dynamic libraries to initialize Vortex plugins.

It is recommended to use the default() method instead provided by the main vortex crate.

pub fn with<V: SessionVar + Default>(self) -> Self

Inserts a new session variable of type V with its default value.
