Enum GroupKey 

pub enum GroupKey {
    Unqualified(String),
    Qualified {
        alias: String,
        field: String,
    },
}

A single GROUP BY key.

Unqualified covers the classic single-table form group .status, whose field name is resolved against the input columns by an exact match first and a unique .field suffix match second (so it also works over a join whose output columns are named alias.field).

Qualified covers the join form group u.status; it resolves exactly to the alias.field output column and never suffix-matches.

Variants

Unqualified(String)

Qualified

Fields

alias: String

field: String

Implementations

impl GroupKey

pub fn output_name(&self) -> String

Name of the output column this key produces. Unqualified keys keep their bare field name; qualified keys are emitted as alias.field so HAVING and downstream projections can reference them consistently.
