[−][src]Struct cassandra_cpp::FunctionMeta
The metadata for a function
Implementations
impl FunctionMeta
[src]
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.
