Trait Resolver 

pub trait Resolver {
    // Required method
    fn resolve(&mut self, r: &Ref) -> Value;
}

Resolves a Ref to the Value it points at.

Implementors own all workbook semantics: missing sheets, undefined names, empty cells, and range materialization. See the module docs for the expected error mapping (#REF! for missing sheets, #NAME? for undefined names). The evaluator only calls this for references that are not shadowed by a local binding such as a LAMBDA parameter.

Required Methods

fn resolve(&mut self, r: &Ref) -> Value

Return the value of r. The receiver is &mut self so resolvers may memoize, count reads, or lazily materialize ranges.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
