Struct DeriveExamplePackSpec 

pub struct DeriveExamplePackSpec<'a, T: CompileToCrate + ?Sized> {
    pub derive_crate_name: String,
    pub trait_name: String,
    pub spec: &'a T,
    pub extra_consumer_imports: Vec<String>,
    pub auxiliary_trait_crates: Vec<(String, String)>,
    pub examples: Vec<Example>,
}

An example pack — a derive Spec + N worked examples.

Fields

derive_crate_name: String

trait_name: String

The trait/derive identifier the consumer writes as #[derive(...)].

spec: &'a T

The derive Spec under test.

extra_consumer_imports: Vec<String>

Imports the consumer needs in addition to the derive crate — e.g. "use my_trait::Marker;" when the derive emits an impl whose trait lives outside the derive crate. One per line.

auxiliary_trait_crates: Vec<(String, String)>

Trait crates the consumer also needs. Path-deps in the consumer Cargo.toml. Each tuple is (crate_name, src_lib_rs_contents).

examples: Vec<Example>

The worked examples.

Implementations

impl<'a, T: CompileToCrate + ?Sized> DeriveExamplePackSpec<'a, T>

pub fn run_under(&self, root: &Path) -> Result<PackRunReport, AstError>

Materialize the derive crate + every auxiliary trait crate + one consumer crate per Example under root. Drives cargo test against the consumer; returns true on success.
