Struct ResolvedProjection 

pub struct ResolvedProjection {
    pub expr: ResolvedExpr,
    pub output: VarId,
    pub name: Arc<str>,
    pub explicit_alias: bool,
    pub span: Span,
}

Fields

expr: ResolvedExpr

output: VarId

name: Arc<str>

Output column name. Arc<str> because executors stamp it onto every produced row; cloning it per row is a refcount bump rather than a heap allocation per cell.

explicit_alias: bool

True when the name came from an explicit AS alias.

span: Span
