Trait LookupObject

pub trait LookupObject {
    // Required method
    fn for_each_entry<R>(
        &self,
        ctx: &LookupCtx<'_>,
        f: &mut impl FnMut(&str, LookupResult) -> Option<R>,
    ) -> Option<R>;

    // Provided method
    fn lookup(&self, ctx: &LookupCtx<'_>, name: &str) -> Option<LookupResult> { ... }
}

Represent an object which has properties which can be accessible

Required Methods

fn for_each_entry<R>( &self, ctx: &LookupCtx<'_>, f: &mut impl FnMut(&str, LookupResult) -> Option<R>, ) -> Option<R>

Will call the function for each entry (useful for completion) If the function return Some, it will immediately be returned and not called further

Provided Methods

fn lookup(&self, ctx: &LookupCtx<'_>, name: &str) -> Option<LookupResult>

Perform a lookup of a given identifier. One does not have to re-implement unless we can make it faster

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
