Implementations

impl Parameter

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

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

Trait Implementations

impl Clone for Parameter

fn clone(&self) -> Parameter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Parameter

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

Formats the value using the given formatter.

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

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl<'a> From<&'a Parameter> for ComparableParameter<'a>

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

Converts to this type from the input type.

impl HasNodeIndex for Parameter

fn node_index(&self) -> &AtomicNodeIndex

Returns the AtomicNodeIndex for this node.

impl Identifier for Parameter

fn identifier(&self) -> TextRange

Return the TextRange for the identifier defining an Parameter.

For example, return the range of x in:

def f(x: int):
    ...

impl PartialEq for Parameter

fn eq(&self, other: &Parameter) -> 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 Parameter

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 Parameter

type Error = ()

The type returned in the event of a conversion error.

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

Performs the conversion.
