Struct Arguments

pub struct Arguments {
    pub posonlyargs: Vec<Parameter>,
    pub args: Vec<Parameter>,
    pub vararg: Option<Parameter>,
    pub kwonlyargs: Vec<Parameter>,
    pub kw_defaults: Vec<Option<Box<ExprType>>>,
    pub kwarg: Option<Parameter>,
    pub defaults: Vec<Box<ExprType>>,
}

Comprehensive function arguments structure supporting all Python argument types.

Fields

posonlyargs: Vec<Parameter>

Positional-only parameters (before / in Python 3.8+)

args: Vec<Parameter>

Regular positional parameters

vararg: Option<Parameter>

Variable positional parameter (*args)

kwonlyargs: Vec<Parameter>

Keyword-only parameters (after * or *args)

kw_defaults: Vec<Option<Box<ExprType>>>

Default values for keyword-only parameters (None = required)

kwarg: Option<Parameter>

Variable keyword parameter (**kwargs)

defaults: Vec<Box<ExprType>>

Default values for regular positional parameters

Trait Implementations

impl Clone for Arguments

fn clone(&self) -> Arguments

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CodeGen for Arguments

type Context = CodeGenContext

A type, generally an enum, that passes the code generator the context of the node.

type Options = PythonOptions

A struct representing the set of compilation options.

type SymbolTable = SymbolTableScopes

A trait for a symbol table

fn to_rust( self, ctx: Self::Context, options: Self::Options, symbols: Self::SymbolTable, ) -> Result<TokenStream, Box<dyn Error>>

A trait method to output Rust code in a general sense. The output should be stream of Rust tokens, however, it is not guaranteed that it will fully compile because of scoping errors and other checks that don’t occur until later.

fn find_symbols(self, symbols_in: Self::SymbolTable) -> Self::SymbolTable

A default implementation for find_symbols(), which simply returns the input. Language nodes that modify the symbol table should override this method.

fn get_docstring(&self) -> Option<String>

A trait method for extracting a docstring from an object that can have a docstring.

impl Debug for Arguments

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Arguments

fn default() -> Arguments

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Arguments

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> FromPyObject<'a> for Arguments

fn extract_bound(ob: &Bound<'a, PyAny>) -> PyResult<Self>

Extracts Self from the bound smart pointer obj.

impl PartialEq for Arguments

fn eq(&self, other: &Arguments) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Arguments

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
