Enum LellmError 

pub enum LellmError {
    Llm(LlmError),
    Tool(ToolError),
    Memory(MemoryError),
    Parse(ParseError),
}

lellm 顶层错误类型 — 门面层统一错误出口。

架构归属： lellm facade crate（聚合各子层错误） 代码位置： lellm-core（暂留，便于 #[from] 跨 crate 转换）

铁律：Core 公共 API 禁止返回 LellmError。 各层必须返回各自的领域错误：

• Provider API → Result<T, LlmError>
• Tool 执行 → Result<T, ToolError>
• 记忆操作 → Result<T, MemoryError>
• 解析操作 → Result<T, ParseError>

迁移计划： 等 facade 承担业务逻辑时，移至 lellm/src/error.rs。

Trait Implementations

impl Debug for LellmError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for LellmError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for LellmError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
