Installation

html-conform is published on crates.io, as a library and, with the cli feature, as a command-line tool.

Add the crate

cargo add html-conform

or in Cargo.toml:

[dependencies]
html-conform = "0.8"

Requirements

Rust 1.88 or newer, as declared in Cargo.toml (rust-version = "1.88.0", edition 2024).
Nothing at runtime. The HTML schema (as a serialized, already compiled pattern) and the Schematron rules are embedded in the crate, so there are no files to ship next to your binary, and no Java, subprocess or network access is involved.

Command line

The crate also builds a command-line tool, behind the cli feature (off by default, no extra dependency):

cargo install html-conform --features cli
html-conform dist/

See Command line for options, exit codes and the SARIF and JUnit output. To check documents from your own code, call the library as the Quickstart shows.
