Struct RuleColumnMetadata 

Source 
pub struct RuleColumnMetadata {
    pub ty: ColumnType,
    pub collation_oid: Option<u32>,
    pub uses_document_id: bool,
    pub position: usize,
}

Implementations§

Source§

impl RuleColumnMetadata

Source

pub fn bind_input(&self, expression: ScalarExpr) -> ScalarExpr

A projected OLD/NEW field is still a column of the event relation. Its source expression cannot export explicit collation strength across that boundary.
