Struct InMemoryLoader 

pub struct InMemoryLoader { /* private fields */ }

In-memory loader keyed by href. Useful for tests and for embedding the ISO Schematron pipeline (where the skeleton stylesheets are bundled into the binary rather than loaded from disk).

Implementations

impl InMemoryLoader

pub fn new() -> InMemoryLoader

pub fn with( self, href: impl Into<String>, text: impl Into<String>, ) -> InMemoryLoader

Register text as the contents of href. Returns self for chained insertion.

pub fn insert(&mut self, href: impl Into<String>, text: impl Into<String>)

Mutable insertion — same as .with(...) but in-place.

Trait Implementations

impl Clone for InMemoryLoader

fn clone(&self) -> InMemoryLoader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InMemoryLoader

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

Formats the value using the given formatter.

impl Default for InMemoryLoader

fn default() -> InMemoryLoader

Returns the “default value” for a type.

impl Loader for InMemoryLoader

fn load(&self, href: &str, _base: Option<&str>) -> Result<String, XsltError>

Load href’s contents. Returns the raw source as a UTF-8 string. Implementations should resolve href against base when href is relative.

fn load_parsed( &self, href: &str, base: Option<&str>, ) -> Result<Arc<Document>, XsltError>

Load href’s contents and return them as a parsed sup_xml_tree::dom::Document. Default implementation calls Self::load and parses fresh each time; loaders that expect repeated lookups for the same URI (filesystem, in-memory) should override to cache the parse result internally so the runtime doc() path doesn’t re-parse the same XML thousands of times across an apply sweep.

fn resolve(&self, href: &str, base: Option<&str>) -> Result<String, XsltError>

Compute the base URI to use for files imported FROM the resource at href. Default: returns href itself (used as the base for the next level of resolution).

fn enumerate(&self, base: Option<&str>) -> Vec<String>

Enumerate every URI the loader can serve. Returned as hrefs that, when passed to Self::load with the same base, succeed. Called by the XSLT runtime when the stylesheet uses a dynamic document() / doc() URI (computed via concat / variables / @attr) — every enumerated URI is speculatively pre-loaded so that the runtime call can resolve against the pre-loaded map.
