Struct LocalValue 

pub struct LocalValue {
    pub id: u64,
    pub name: String,
    pub type_name: String,
    pub value: String,
    pub kind: LocalKind,
    pub source: SourceLocation,
    pub frame_id: Option<u64>,
    pub observation: Observation,
}

A value captured or inferred for a single invocation. 单次调用中捕获或推断的值。

observation is Unobserved for MIR-only locals. Such values describe a possible binding and never claim that a runtime value was seen. observation 为 Unobserved 时表示仅由 MIR 推断，不能当作运行时实值。

Fields

id: u64

The trace-local id; equal ids mean the same captured value. 追踪内的局部 id；id 相等即同一个已捕获值。

name: String

The name used in output, function::name for inferred locals. 输出中使用的名称；推断局部值为 function::name。

type_name: String

The rendered type name reported by the recorder. 记录方给出的渲染后类型名。

value: String

The rendered value, <not observed> for MIR-only locals. 渲染后的值；仅由 MIR 得出的局部值为 <not observed>。

kind: LocalKind

The role this value plays in its invocation. 该值在其调用中扮演的角色。

source: SourceLocation

Where the value was recorded or inferred. 该值被记录或推断的位置。

frame_id: Option<u64>

The enclosing frame, None when recorded outside every traced call. 所属调用帧；在任何被追踪调用之外记录时为 None。

observation: Observation

Whether the value was observed at runtime or inferred statically. 该值是运行时观测到的还是静态推断出来的。
