Struct LayeredLoader 

pub struct LayeredLoader<P: PackLoader, S: PackLoader> {
    pub primary: P,
    pub secondary: S,
}

Loader that delegates to a primary loader and falls back to a secondary one when the primary returns “not found”. The CLI uses this with the workspace packs/ directory as primary and EmbeddedLoader as secondary, so workspace-vendored packs always shadow built-ins of the same name.

Fields

primary: P

Primary lookup; takes precedence over secondary.

secondary: S

Fallback lookup, used when primary.load(...) returns Err.

Implementations

impl<P: PackLoader, S: PackLoader> LayeredLoader<P, S>

pub fn new(primary: P, secondary: S) -> Self

Builds a layered loader from any pair of primary / secondary loaders.

Trait Implementations

impl<P: PackLoader, S: PackLoader> PackLoader for LayeredLoader<P, S>

fn load(&self, name: &str) -> Result<String, String>

Returns the raw YAML source for the pack named name or a human-readable error message if it cannot be located.
