Struct ParameterWithDefault 

pub struct ParameterWithDefault {
    pub range: TextRange,
    pub node_index: AtomicNodeIndex,
    pub parameter: Parameter,
    pub default: Option<Box<Expr>>,
}

An alternative type of AST arg. This is used for each function argument that might have a default value. Used by Arguments original type.

NOTE: This type is different from original Python AST.

Fields

range: TextRange

node_index: AtomicNodeIndex

parameter: Parameter

default: Option<Box<Expr>>

Implementations

impl ParameterWithDefault

pub fn default(&self) -> Option<&Expr>

pub const fn name(&self) -> &Identifier

pub fn annotation(&self) -> Option<&Expr>

pub fn uses_pep_484_positional_only_convention(&self) -> bool

Return true if the parameter name uses the pre-PEP-570 convention (specified in PEP 484) to indicate to a type checker that it should be treated as positional-only.

Trait Implementations

impl Clone for ParameterWithDefault

fn clone(&self) -> ParameterWithDefault

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParameterWithDefault

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

Formats the value using the given formatter.

impl<'a> From<&'a ParameterWithDefault> for AnyNodeRef<'a>

fn from(node: &'a ParameterWithDefault) -> AnyNodeRef<'a>

Converts to this type from the input type.

impl<'a> From<&'a ParameterWithDefault> for AnyRootNodeRef<'a>

fn from(node: &'a ParameterWithDefault) -> AnyRootNodeRef<'a>

Converts to this type from the input type.

impl<'a> From<&'a ParameterWithDefault> for ComparableParameterWithDefault<'a>

fn from(arg: &'a ParameterWithDefault) -> Self

Converts to this type from the input type.

impl HasNodeIndex for ParameterWithDefault

fn node_index(&self) -> &AtomicNodeIndex

Returns the AtomicNodeIndex for this node.

impl Identifier for ParameterWithDefault

fn identifier(&self) -> TextRange

Return the TextRange for the identifier defining an ParameterWithDefault.

For example, return the range of x in:

def f(x: int = 0):
    ...

impl PartialEq for ParameterWithDefault

fn eq(&self, other: &ParameterWithDefault) -> 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 Ranged for ParameterWithDefault

fn range(&self) -> TextRange

The range of this item in the source text.

fn start(&self) -> TextSize

The start offset of this item in the source text.

fn end(&self) -> TextSize

The end offset of this item in the source text.

impl<'a> TryFrom<AnyRootNodeRef<'a>> for &'a ParameterWithDefault

type Error = ()

The type returned in the event of a conversion error.

fn try_from(node: AnyRootNodeRef<'a>) -> Result<&'a ParameterWithDefault, ()>

Performs the conversion.
