seam-server

Rust implementation of the SeamJS server core, defining procedures, subscriptions, pages, and an HTML template injector. Built on axum.

Structure

src/lib.rs — SeamType trait and primitive JTD schema implementations
src/server.rs — SeamServer builder and axum route handlers
src/procedure.rs — ProcedureDef / SubscriptionDef type aliases
src/page.rs — PageDef / LoaderDef types
src/manifest.rs — Build JSON manifest from procedure and subscription definitions
src/errors.rs — SeamError struct (open code + status)
src/injector/ — HTML template engine (tokenize, parse, render)

Directive	Purpose
`<!--seam:path-->`	Text slot (HTML-escaped)
`<!--seam:path:html-->`	Raw HTML slot
`<!--seam:path:attr:name-->`	Inject attribute value
`<!--seam:if:path-->...<!--seam:endif:path-->`	Conditional block
`<!--seam:each:path-->...<!--seam:endeach-->`	Iteration block
`<!--seam:match:path-->...<!--seam:endmatch-->`	Pattern matching block

The SeamType trait maps Rust types to JTD schemas; derive it with #[derive(SeamType)] from seam-macros
The injector pipeline mirrors the TypeScript @canmi/seam-injector but is compiled into this crate
SSE subscriptions use BoxStream for async iteration
