An append-only in-memory database in Rust for rows queried using bit (flag) columns. This database is designed for a very specific use case where you have mostly static data that you typically load at startup and have to query constantly using very simple filters. Datasets like these can...

MemoryKindShim枚举类型用于表示Mir执行器中的内存类型(memory kind)。它将Rust中的内存类型进行桥接,并提供了一些用于处理内存的方法。 通过这些结构体和枚举类型的定义,shim.rs文件提供了一种桥接机制,使得Mir执行器能够与Rust的原生操作进行交互,从而实现Rust代码的执行和评估。 File: rust/src/tools/rust-analyzer/...
DataFusion is an extensible query engine written in Rust that uses Apache Arrow as its in-memory format. This crate provides libraries and binaries for developers building fast and feature rich database and analytic systems, customized to particular workloads. See use cases for examples. The follow...
Rust is known for its memory safety and zero-cost abstractions, which make it a good choice for building high-performance, reliable, and secure software. It’s particularly well-suited for system programming, web development, and embedded systems. ...

上面的例子中使用create_in_memory创建的数据可存在数据持久化问题,当然你也可以存储在磁盘中。我们可以使用create和open的方式进行读写操作 pub fn create(&self, path: impl AsRef<Path>) -> Result<Database, DatabaseError> ❝ 如果文件不存在,或者是一个空文件,那么它将在其中初始化一个新的数据库。如...
