Trait Scaffolder 

pub trait Scaffolder {
    // Required methods
    fn target_id(&self) -> &'static str;
    fn scaffold(
        &self,
        ctx: &ScaffoldContext<'_>,
    ) -> Result<Vec<OutputFile>, ScaffoldError>;
}

Produces project-mode scaffolding files for one target.

A Scaffolder adds files alongside the emitted source tree — manifests, README, formatter/linter configs, transpiled tests. It runs only in project mode (never --source-only); the build driver enforces that.

Returned OutputFiles use paths relative to the target build root (build/<target>/), the same convention as crate::CodeGenerator::generate_project. A scaffolder must not emit a file at a path the codegen tree already occupies (e.g. the run-affordance Cargo.toml/go.mod/package.json); run_scaffolder drops any such collisions defensively, but scaffolders should avoid them.

Required Methods

fn target_id(&self) -> &'static str

The target id this scaffolder serves.

fn scaffold( &self, ctx: &ScaffoldContext<'_>, ) -> Result<Vec<OutputFile>, ScaffoldError>

Produce the additional scaffolding files for ctx.

Errors

Returns ScaffoldError if scaffolding cannot be produced (e.g. an internally inconsistent config). S5 stubs do not error.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
