Struct FilesystemLoader 

pub struct FilesystemLoader { /* private fields */ }

Implementations

impl FilesystemLoader

pub fn new(allowed_roots: Vec<PathBuf>) -> FilesystemLoader

Construct a loader scoped to the given root directories. Files outside these roots — even when the href is absolute and points at them directly — will be refused.

Pass specific directories like the stylesheet’s own folder or /usr/share/xml; never pass /. An empty list means “refuse everything,” which is the safest choice for an untrusted stylesheet that’s not expected to import.

Trait Implementations

impl Debug for FilesystemLoader

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

Formats the value using the given formatter.

impl Default for FilesystemLoader

fn default() -> FilesystemLoader

Returns the “default value” for a type.

impl Loader for FilesystemLoader

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

Cached parse for repeated lookups of the same on-disk file. Keys on the canonical path so foo/../foo.xml and foo.xml (resolved against the same base) share a cache entry. Misses fall through to load + parse_str then populate the cache.

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

Walk every file under the loader’s allowed roots, returning hrefs relative to base’s parent directory. Only files whose extension is a typical XML / text resource are returned, to keep speculative pre-loading from chewing through every binary the test directory happens to contain. Bounded depth (16) so a stray symlink loop can’t hang the runtime.

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 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).
