DevState

docgen_build::incremental

Struct DevState 

Source 
pub struct DevState { /* private fields */ }
Expand description

The dev server’s persistent incremental build engine. Holds the renderer and the last full build’s artifacts; rebuild takes the fast path when it can prove equivalence and falls back to a full build otherwise.

Implementations§

Source§

impl DevState

Source

pub fn initial(project_root: &Path, out_dir: &Path) -> Result<(Self, Rebuilt)>

Run the initial full build (Dev mode) and seed the engine from it.

Source

pub fn rebuild(&mut self) -> Result<Rebuilt>

Rebuild after a filesystem change. Re-discovers the docs and takes the fast path (re-render only changed pages) when the change is provably non- structural; otherwise falls back to a full build and re-seeds the cache.
