Struct RowSet 

pub struct RowSet<'a> {
    pub view: String,
    pub groups: Vec<Group<'a>>,
    pub ungrouped: Vec<&'a Row>,
}

A selection projected into groups.

Fields

view: String

The name of the view that produced this.

groups: Vec<Group<'a>>

Groups, ascending by key.

ungrouped: Vec<&'a Row>

Documents in scope that no field in the grouping chain gave a usable value for.

Reported rather than dropped: a view whose entries have all quietly stopped grouping looks exactly like an empty archive, and the difference is the whole diagnosis. A frontend labels this bucket (“Undated”, “Untagged”); which words to use is a presentation decision this crate does not make.

Implementations

impl RowSet<'_>

pub fn len(&self) -> usize

How many documents this row set covers.

Not the number of rows printed: a document under two of a multi-valued field’s groups is one document in two places, and counting it twice is how a view comes to claim more entries than the workspace has. The placements are placements.

pub fn is_empty(&self) -> bool

Whether the view grouped nothing at all.

pub fn placements(&self) -> usize

How many rows a renderer will draw — one per document per group it falls into, which is what makes it different from len.
