ⓘImportant traits for FieldIterator
pub fn fields_iter(&self) -> FieldIterator | [src] |
Iterator over the fields in this function
pub fn get_name(&self) -> String | [src] |
Gets the name of the function.
pub fn full_name(&self) -> String | [src] |
Gets the full name of the function. The full name includes the function's name and the function's signature: "name(type1 type2.. typeN)".
pub fn body(&self) -> String | [src] |
Gets the body of the function.
pub fn language(&self) -> String | [src] |
Gets the language of the function.
pub fn called_on_null_input(&self) -> bool | [src] |
Gets whether a function is called on "null".
pub fn argument_count(&self) -> usize | [src] |
Gets the number of arguments this function takes.
pub fn argument(&self, index: usize) -> Result<()> | [src] |
Gets the function's argument name and type for the provided index.
pub fn argument_type_by_name(&self, name: &str) -> ConstDataType | [src] |
Gets the function's argument and type for the provided name.
pub fn return_type(&self) -> ConstDataType | [src] |
Gets the return type of the function.
pub fn field_by_name(&self, name: &str) -> Value | [src] |
Gets a metadata field for the provided name. Metadata fields allow direct access to the column data found in the underlying "functions" metadata table.
