root-io
provides basic support for reading data stored in binary .root
files commonly used in particle physics experiments. This crates provides:
- Core types and parsers to read the layout description of custom classes contained in a given file
- Tools to generate
yaml
describing the streamed objects (aka.TStreamerInfo
) - Tools to generate (buggy)
Rust
code as a starting point for a new parser - Set of types and parsers needed to read so-called
TTree
s
The majority of the exposed API serves the latter point; striving to enable an easy iteration over data stored in TTree
s. In particular, root-io
supports reading TBranches
(i.e. akin to "columns" of a database) with a variable number of elements in each entry (i.e. TBranches
of TClonesArray
).
The root-ls
crate utilizes this crate to in a CLI to inspect a given root file and to deploy the code-gen tools.
