Struct EdgeColumnBatch 

Source 
pub struct EdgeColumnBatch {
    pub srcs: Vec<VertexId>,
    pub dsts: Vec<VertexId>,
    pub edge_types: Vec<String>,
    pub rankings: Vec<i64>,
    pub columns: Vec<PropertyColumn>,
}
Expand description

A column-major edge batch produced by EdgeCursor::next_column_batch.

Rows are implicit: every column (and srcs/dsts/edge_types/ rankings) has the same length. columns holds one entry per requested property in projection order.
