How to reset Rust Embedded Database with cargo project?

Hello, everyone. May I ask your help? I want to reset redb (rust embedded database) in my project. I deleted all blocks in bitcoin core. But the table is existing so that Rust code open table and shows the result on the website. Then when I clicked the content error comes because in fact there is no block which should be connected to the table content.
If I delete the redb file then the cargo recreate the redb file using mempool ( I think that is mempool but I wonder.). How could I reset this redb? Thanks.
