Implementations

impl TableSpec

pub fn validate(&self) -> Result<()>

Validates bounded table structure.

pub fn style_for(&self, row: &DataRow) -> Result<Style>

Computes the ordered conditional style layers for one row.

pub fn visit_bounded( &self, dataset: &dyn Dataset, visitor: &mut dyn FnMut(u64, &DataRow) -> Result<()>, ) -> Result<()>

Streams rows with an enforced hard maximum.

pub fn visit_bounded_until( &self, dataset: &dyn Dataset, visitor: &mut dyn FnMut(u64, &DataRow) -> Result<bool>, ) -> Result<()>

Streams rows until a bounded visitor asks to stop.
