Struct CaseContext 

pub struct CaseContext<'a> {
    pub index: &'a Index,
}

What a case provider may look at: the repository’s index, so that a case can name an object that exists (objects.get needs a real URI) and skip itself when the repository holds nothing it could ask for.

Fields

index: &'a Index

The index of the repository the benchmark runs against.

Implementations

impl<'a> CaseContext<'a>

pub fn of(ctx: &'a Context) -> Self

The case context of a live context: what a caller that holds a crate::capability::Context hands to a case provider.

It exists so that reaching a provider does not require reaching into the index at the call site. A benchmark case is declared against the index by design — the vocabulary above says why — and a caller that only wants to run the declaration should not have to open the index to do it, because a page that opens the index has no way of being told apart from a page that reads it (ADR 0012).
