One of the currently supported TREXIO open modes.
For example, 'r' or 'w'.
state: int
Active state of the file (needed to write $group_dset$).
Active (excited or ground) state of the file.
Default is 0.
isOpen: bool
Flag indicating whether the current object is still open for I/O

** File state
~trexio_set_state~ set an existing ~trexio_t~ file handle to a given state.
**Note:** the use of the functions below is discouraged as of version 2.3.0.
Please use ~trexio_write_state_id~ and ~trexio_read_state_id~ to get the state
corresponding to a given ~trexio_t~ file. There can be only one ~state_id~ per file,
namely data for excited state wave functions have to go in a file different from
the ground state one (see the ~state~ group description for more info about how
you can link the ground state TREXIO file with its excited states).
~trexio_set_state~ set an existing ~trexio_t~ file handle to a given state
and write it as ~state_id~ attribute.
~trexio_get_state~ returns current state of the ~trexio_t~ file handle.
input parameters:
~file~ -- TREXIO file handle.
~state~ -- ~int32_t~ number of state.
~state~ -- ~int32_t~ ID of a state (0 for ground state).
output:
~trexio_exit_code~ exit code.
