Function args_hash

src/context/read_cache.rs:41–46

Computes a stable hash of the per-call arguments that affect output. Used as the `args_hash` cache-key component so two calls with different `lines` or `limit` values map to distinct rows.

(args: &serde_json::Value)

/// as the `args_hash` cache-key component so two calls with different `lines`
/// or `limit` values map to distinct rows.
pub fn args_hash(args: &serde_json::Value) -> String {
    let canonical = canonicalize(args);
    let mut hasher = Sha256::new();
    hasher.update(canonical.as_bytes());
    hex::encode(hasher.finalize())
}

/// Sorts JSON object keys recursively so two semantically-equal arg objects
/// hash identically regardless of key insertion order.
