ViewBuilder

Struct ViewBuilder 

Source
pub struct ViewBuilder<'a> { /* private fields */ }
Expand description

视图构建器:持有源表 gather 句柄与槽宽,提供随机采样构建和调用方访问序构建。

Implementations§

Source§

impl<'a> ViewBuilder<'a>

Source

pub fn new(batch: &'a BadgeGather<'a>, slot_bytes: u64) -> Self

Source

pub fn build_random( &self, n: usize, view_out: &Path, keys_out: Option<&Path>, ) -> Result<f64>

随机采样构建(原有 LCG 路径)。

Source

pub fn build_from_keys( &self, keys: &[u64], view_out: &Path, keys_out: Option<&Path>, ) -> Result<f64>

按调用方提供的 rowid 访问序构建。
