pub struct WindowUDFFieldArgs<'a> { /* private fields */ }Expand description
Metadata for defining the result field from evaluating a user-defined window function.
Implementations§
Source§impl<'a> WindowUDFFieldArgs<'a>
impl<'a> WindowUDFFieldArgs<'a>
Sourcepub fn new(
input_types: &'a [DataType],
display_name: &'a str,
) -> WindowUDFFieldArgs<'a>
pub fn new( input_types: &'a [DataType], display_name: &'a str, ) -> WindowUDFFieldArgs<'a>
Create an instance of WindowUDFFieldArgs.
§Arguments
input_types- The data types corresponding to the arguments to the user-defined window function.function_name- The qualified schema name of the user-defined window function expression.
Sourcepub fn input_types(&self) -> &[DataType]
pub fn input_types(&self) -> &[DataType]
Returns the data type of input expressions passed as arguments to the user-defined window function.
Sourcepub fn name(&self) -> &str
pub fn name(&self) -> &str
Returns the name for the field of the final result of evaluating the user-defined window function.
Sourcepub fn get_input_type(&self, index: usize) -> Option<DataType>
pub fn get_input_type(&self, index: usize) -> Option<DataType>
Returns Some(DataType) of input expression at index, otherwise
returns None if the index is out of bounds.
