//! Error types for `redis-vl`.
//!
//! All fallible public APIs return `Result<T, Error>`. The [`Error`] enum
//! wraps underlying Redis, JSON, YAML, HTTP, I/O errors as well as
//! domain-specific schema validation and input errors.

/// Result alias used throughout the crate.
pub type Result<T> = std::result::Result<T, Error>;

/// Errors returned by RedisVL operations.
#[derive(Debug, thiserror::Error)]
pub enum Error {
    /// Wrapper for Redis transport errors.
    #[error("redis error: {0}")]
    Redis(#[from] redis::RedisError),
    /// Wrapper for JSON serialization and parsing errors.
    #[error("json error: {0}")]
    Json(#[from] serde_json::Error),
    /// Wrapper for YAML serialization and parsing errors.
    #[error("yaml error: {0}")]
    Yaml(#[from] serde_yaml::Error),
    /// Wrapper for HTTP client errors.
    #[error("http error: {0}")]
