Struct FingerprintPlugin 

pub struct FingerprintPlugin;

Plugin that fingerprints CSS/JS assets and rewrites HTML references.

Runs in after_compile:

1. Hash each .css and .js file (SHA-256, first 8 hex chars)
2. Rename: style.css → style.a1b2c3d4.css
3. Rewrite all HTML <link> and <script> references
4. Add integrity and crossorigin attributes (SRI)

The SRI digest algorithm defaults to SHA-384 and is configurable via [security] sri_algorithm in ssg.toml (v0.0.47 plan §3 item 2.3). The cache-busting filename fingerprint stays SHA-256 regardless — it is not a security control.

Trait Implementations

impl Clone for FingerprintPlugin

fn clone(&self) -> FingerprintPlugin

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for FingerprintPlugin

impl Debug for FingerprintPlugin

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Plugin for FingerprintPlugin

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

Returns the unique name of this plugin.

fn after_compile(&self, ctx: &PluginContext) -> Result<(), SsgError>

Called after site compilation completes.

fn before_compile(&self, _ctx: &PluginContext) -> Result<(), SsgError>

Called before site compilation begins.

fn transform_html( &self, html: &str, _path: &Path, _ctx: &PluginContext, ) -> Result<String, SsgError>

Per-file HTML transform hook — called once per HTML file during the fused transform pass.

fn has_transform(&self) -> bool

Returns true if this plugin implements transform_html. Override to true to opt in to the fused transform pass.

fn needs_all_files(&self) -> bool

Returns true if this plugin must always observe the full cache.html_files() list — even during --incremental rebuilds that only invalidated a handful of pages.

fn on_serve(&self, _ctx: &PluginContext) -> Result<(), SsgError>

Called before the development server starts serving files.
