Struct AnalysisHost 

pub struct AnalysisHost { /* private fields */ }

The single mutable owner of analysis state — one per project/workspace.

The input world is a virtual file system (FileId → UTF-8 text) held as salsa inputs; the host never reads paths. Clients push text via AnalysisHost::apply_change.

Implementations

impl AnalysisHost

pub fn new() -> Self

A new, empty host.

pub fn apply_change(&mut self, change: Change)

Apply a batch of input changes. The only mutation entry point — each set/remove bumps the salsa revision (and cancels any in-flight reads on outstanding Analysis handles). Edited files are LOW durability (they change every keystroke).

pub fn set_engine_api(&mut self, bytes: &[u8]) -> bool

Install a runtime-fetched engine model — the wasm path (an extension_api blob the host fetched and brotli-decoded, decoded here via EngineApi::from_bytes). Native builds use the bundled model and normally never call this. Returns false (rather than panicking) if the bytes fail to decode, leaving the model unset. First install wins (load-once); installing it after queries have already run correctly recomputes them — the wasm engine-generation input invalidates the affected reads, so loading the blob async (after opening a document) is safe, not just loading it first.

pub fn analysis(&self) -> Analysis

A cheap, cloneable, Send snapshot for read queries (a cloned salsa database handle).
