Struct IncludeResolver 

pub struct IncludeResolver(/* private fields */);

Resolver closure stored on crate::ParserConfig.

Wraps an Arc<dyn Fn> so the type is Clone + Debug (the underlying dyn Fn is not). Construct with IncludeResolver::new.

Arc (not Box) keeps configs cheap to clone. The closure is Send + Sync so the resolver can be invoked from any thread of a parallel parse.

Implementations

impl IncludeResolver

pub fn new<F>(f: F) -> Self

where F: Fn(IncludeRequest<'_>) -> Result<InputSource> + Send + Sync + 'static,

Wrap a closure as an IncludeResolver.

Examples

use noyalib::include::{IncludeRequest, IncludeResolver, InputSource};
use noyalib::Result;
let r = IncludeResolver::new(|req: IncludeRequest<'_>| -> Result<InputSource> {
    Ok(InputSource::new(req.spec, "v: 1\n"))
});
let _ = r;

pub fn resolve(&self, req: IncludeRequest<'_>) -> Result<InputSource>

Invoke the wrapped closure.

Errors

Surfaces whatever the underlying resolver returned.
