Installation
Which crates a tool needs and which Rust version they build with.
The crates are on crates.io and require Rust 1.85 or newer. Which of them a project includes depends on what it wants to do.
Running rules
cargo add a11y-rules@0.26.1 a11y-dom@0.26.0 a11y-report@0.26.0a11y-rules provides the rules and the entry functions run, run_with_semantics,
run_with_rendering and run_full. You need a11y-dom for the document model and a11y-report
for the report the rules return.
Computing the accessible name
cargo add accname@0.26.1 a11y-dom@0.26.0accname is generic over the document model from a11y-dom and can be used without the rules.
A host that does not provide the role and name itself plugs it into its
Semantics implementation, see Quick start.
Just the report model
cargo add a11y-report@0.26.1For tools that have their own checks but want to speak the same JSON contract.
a11y-report depends only on serde.
Versions
The four crates are versioned in lockstep. A breaking change in any one of them raises all four to the same minor version. New rule IDs also count as a minor step, because they make findings appear that a consumer has not expected so far.
