Enum weld::ast::BuilderKind

pub enum BuilderKind {
    Appender(Box<Type>),
    Merger(Box<Type>, BinOpKind),
    DictMerger(Box<Type>, Box<Type>, BinOpKind),
    GroupMerger(Box<Type>, Box<Type>),

}

Builder types in the Weld IR.

Variants

Appender(Box<Type>)

A builder that appends items to a list.

Merger(Box<Type>, BinOpKind)

A builder that constructs a scalar or struct.

Results are merged using an associative binary operator.

DictMerger(Box<Type>, Box<Type>, BinOpKind)

A builder that creates a dictionary.

Results are grouped by key, and values are combined using an associative binary operator.

GroupMerger(Box<Type>, Box<Type>)

A builder that creates groups.

Results are grouped by key, where values are appended to a list.

VecMerger(Box<Type>, BinOpKind)

A builder that constructs a vector by updating elements.

Elements are updated by index using an associative binary operator.
