rudb_functions/
lib.rs

1//! The scalar, aggregate and window function library.
2//!
3//! Rank 7 in the layer rule. See `xtask/layers.toml` and `spec/18-package-layout.md`.
4//!
5//! Most of what is here is the signature half: given a name and the types of the arguments, which
6//! function is that and what does it return. The implementations are separate work and they go
7//! behind the same names, so the binder does not change when they arrive.
8//!
9//! [`mod@file`] is the exception and it reads a file. A table function that scans a Parquet file cannot
10//! be resolved from a table of names, because its columns are in the file, so resolving one means
11//! opening it. That is the only I/O in this crate and it is the reason `rudb-io` and `rudb-parquet`
12//! are dependencies of it.
