Struct OutputConfig

Source

pub struct OutputConfig {
    pub fields: Option<Vec<String>>,
}

Expand description

[output] 配置段：字段投影

Fields§

§fields: Option<Vec<String>>

字段投影：仅导出指定字段，默认为全部 15 个字段

Implementations§

Source §

impl OutputConfig

Source

pub fn field_mask(&self) -> FieldMask

计算字段投影掩码。字段名在 validate() 阶段已验证，无效名称静默退化为全量掩码。

Source

pub fn ordered_field_indices(&self) -> Vec<usize>

按用户配置顺序返回字段索引列表，供 exporter 写入时按序遍历。
