Struct CommonOpts 

pub struct CommonOpts {
    pub model: String,
    pub context_window: usize,
    pub max_tokens: usize,
    pub auto_compress: bool,
    pub scratch: Option<String>,
}

请求级公共配置，内嵌于各后端的 Opts 类型。

ContextBackend::Opts 通过 AsRef<CommonOpts> 约束，确保后端 Opts 提供这些字段。 每次请求由调用方显式构造，不提供 Default。

Fields

model: String

模型标识（如 "deepseek-v4-pro"、"glm-4-flash"）。

context_window: usize

模型上下文窗口大小（token 数），用于自动压缩检测。

max_tokens: usize

最大输出 token 数。

auto_compress: bool

上下文溢出时是否自动压缩。false 时溢出返回错误。

scratch: Option<String>

每轮刷新的临时元数据，发送时作为 system 消息拼接到对话末尾，不存储。

Trait Implementations

impl Clone for CommonOpts

fn clone(&self) -> CommonOpts

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CommonOpts

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

Formats the value using the given formatter.

impl PartialEq for CommonOpts

fn eq(&self, other: &CommonOpts) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
