Python wrapper of ese_parser

Exports all ese_trait interfaces with python functions.

To build wheel, run build_wheel.bat.

Available methods:

• load(str) -> Option<String> - load database, return String in case of error
• open_table(table_str) -> u64 - open table, return table ID
• close_table(table_id) -> bool - close table, return true on success
• get_tables() -> Vec<String> - get array of tables
• get_column(table_str, column_name_str) -> PyColumnInfo
• get_columns(table_str) -> Vec<PyColumnInfo> - where PyColumnInfo is a structure with get methods:

struct PyColumnInfo {
    name: String,
    id: u32,
    typ: u32,
    cbmax: u32,
    cp: u16
}

• move_row(table_id, crow) -> bool - where crow is one of:

JET_MoveFirst = 2147483648;
JET_MovePrevious = -1;
JET_MoveNext = 1;
JET_MoveLast = 2147483647;

• get_value(table_id, column_info) -> Option<PyObject> - will return object or None, if field is NULL
• get_value_mv(table_id, column_info, multi_value_index) -> PyResult<Option<PyObject>> - will return multi-value object at index (itagSequence) or None, if field is NULL

Python wrapper usage sample:

import ese_parser

edb = ese_parser.PyEseDb()
edb.load("../lib/testdata/test.edb")
tables = edb.get_tables()
print("tables: {}".format(tables))

for t in tables:
	tbl = edb.open_table(t)

	print("table {} opened: {}".format(t, tbl))
	columns = edb.get_columns(t)

	for c in columns:
		print("name: {}, id: {}, type: {}, cbmax: {}, cp: {}".format(c.name, c.id, c.typ, c.cbmax, c.cp))

	while True:
		print("|", end='')
		for c in columns:
			i = edb.get_value(tbl, c)
			print(" {} |".format(i), end='')
		print("")
		if not edb.move_row(tbl, 1):
			break
	edb.close_table(tbl)
