Enum Backend 

pub enum Backend {
    ClaudeCodeCli,
    ClaudeAgentSdk,
    CodexLocal,
    Vercel,
}

Which back-end/runtime a case was (or should be) run against. Value domain matches the dispatcher/<name> directory names exactly, so clap’s own unknown-value error already lists every back-end this crate knows the name of — but knowing the name is not the same as having an adapter for it; see resolve_adapter (crate-private) below.

Defaults to Backend::ClaudeCodeCli so an eval invocation that never mentions --backend keeps measuring exactly what it always measured (binding decision: never silently change what an existing invocation reports).

Variants

ClaudeCodeCli

ClaudeAgentSdk

CodexLocal

Vercel

Implementations

impl Backend

pub fn as_str(&self) -> &'static str

The spelling shared by CLI/serde and the cache-key element — identical to the back-end’s dispatcher/<name> directory name.
