Entry Points

Entry points are where messages or queries are handled by the contract.

All three of the following are entry points.

1. Instantiate messages

As defined by the InstantiateMsg struct, are handled by instantiate.

2. Messages

As defined by the ExecuteMsg enum, are handled by the execute function, using a pattern-matching match statement.

3. Queries

As defined by the QueryMsg enum, are handled by the query function, using a pattern-match. execute and query must exhaustively match every variant in the enums they handle, while instantiate only has to deal with the struct it is passed.
