Crate nano_io 

nano-io — ROOT input reading and skim output writing for nano.rust.

Reading wraps the owned synchronous nano-rootio crate for local files and HTTP(S) byte-range sources behind the http feature. Writing uses the owned pure-Rust TTree writer for the fixed skim schema (bool, i32, u32, u64, f32, Vec<f32>) plus filtered Runs/LuminosityBlocks. See docs/rust-migration.md.
