Struct EdgeSchema 

pub struct EdgeSchema {
    pub source_col: usize,
    pub target_col: usize,
    pub predicate_col: Option<usize>,
}

Configuration for edge column layout in a RecordBatch.

Different consumers have different schemas — this struct lets you specify which columns contain source IDs, target IDs, and predicates.

Fields

source_col: usize

Column index for source node ID.

target_col: usize

Column index for target node ID.

predicate_col: Option<usize>

Column index for edge predicate/type (optional — None means “all edges”).

Trait Implementations
