Struct ResourceSnapshot 

pub struct ResourceSnapshot {
    entries: BTreeMap<PathBuf, Result<ResourceData>>,
}

Captured external inputs belonging to one lowering result.

Bytes and failures are retained so consumers interpret external source spans against the same version used by the compiler. This is a per-path snapshot, not an atomic snapshot of the whole filesystem.

Fields

entries: BTreeMap<PathBuf, Result<ResourceData>>

Implementations

impl ResourceSnapshot

pub fn text_index(&self, path: &Path) -> Option<&LineIndex>

Lazily index a captured UTF-8 resource. Repeated lookups reuse the index. Returns None for absent, failed, or non-UTF-8 reads; Self::get retains the original bytes or I/O error. Never rereads the filesystem.

pub fn get(&self, path: &Path) -> Option<Result<&[u8], &Error>>

Look up a captured read. None means the path was never requested.

pub(crate) fn read( &mut self, reader: &dyn ResourceReader, path: &Path, ) -> Result<&[u8], &Error>

pub(crate) fn dependencies(&self) -> Vec<ExternalDependency>
