Struct EdgeTable 

pub struct EdgeTable {
    pub name: String,
    pub table: TableReference,
    pub source: String,
    pub destination: String,
    pub source_vertex: Option<String>,
    pub destination_vertex: Option<String>,
    pub labels: Vec<Label>,
}

An edge table: each row is an edge from source to destination.

Fields

name: String

Its element name: the AS name, or else the table’s name.

table: TableReference

source: String

SOURCE KEY (column).

destination: String

DESTINATION KEY (column).

source_vertex: Option<String>

The vertex table (element name) SOURCE … REFERENCES, if any.

destination_vertex: Option<String>

The vertex table (element name) DESTINATION … REFERENCES, if any.

labels: Vec<Label>

Implementations

impl EdgeTable

pub fn new( table: impl Into<TableReference>, source: impl Into<String>, destination: impl Into<String>, ) -> Self

pub fn labels(&self) -> Cow<'_, [Label]>

Its labels, the default one if none were written.

pub fn answers_to(&self, label: &str) -> bool

Whether label names this table: its element name or one of its labels.
