Struct Parameters 

pub struct Parameters {
    pub positional_only: Vec<Parameter>,
    pub positional_or_keyword: Vec<Parameter>,
    pub keyword_only: Vec<Parameter>,
    pub varargs: Option<Parameter>,
    pub varkw: Option<Parameter>,
}

Container for parameters in a Python function/method signature

This struct organizes parameters into sections according to Python’s signature syntax, ensuring proper ordering and placement of delimiters (/ and *).

Fields

positional_only: Vec<Parameter>

Positional-only parameters (before /)

positional_or_keyword: Vec<Parameter>

Positional or keyword parameters

keyword_only: Vec<Parameter>

Keyword-only parameters (after *)

varargs: Option<Parameter>

Variable positional parameter (*args)

varkw: Option<Parameter>

Variable keyword parameter (**kwargs)

Implementations

impl Parameters

pub fn new() -> Self

Create an empty Parameters container

pub fn from_infos(infos: &[ParameterInfo]) -> Self

Build Parameters from a slice of ParameterInfo

pub fn iter_entries(&self) -> impl Iterator<Item = &Parameter>

Iterate over all parameters in signature order

pub fn is_empty(&self) -> bool

Check if there are no parameters at all

Trait Implementations

impl Clone for Parameters

fn clone(&self) -> Parameters

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Parameters

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

Formats the value using the given formatter.

impl Default for Parameters

fn default() -> Self

Returns the “default value” for a type.

impl Display for Parameters

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

Formats the value using the given formatter.

impl Import for Parameters

fn import(&self) -> HashSet<ImportRef>

impl PartialEq for Parameters

fn eq(&self, other: &Parameters) -> 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.
