[−][src]Enum datafusion::physical_plan::functions::Signature

pub enum Signature {
    Variadic(Vec<DataType>),
    VariadicEqual,
    Uniform(usize, Vec<DataType>),
    Exact(Vec<DataType>),
    Any(usize),
}

A function's signature, which defines the function's supported argument types.

Variants

Variadic(Vec<DataType>)

arbitrary number of arguments of an common type out of a list of valid types

VariadicEqual

arbitrary number of arguments of an arbitrary but equal type

Uniform(usize, Vec<DataType>)

fixed number of arguments of an arbitrary but equal type out of a list of valid types

Exact(Vec<DataType>)

exact number of arguments of an exact type

Any(usize)

fixed number of arguments of arbitrary types
