Struct MathAttach 

pub struct MathAttach<'a>(/* private fields */);

A base with optional attachments in math: a_1^2.

Implementations

impl<'a> MathAttach<'a>

pub fn base(self) -> Expr<'a>

The base, to which things are attached.

pub fn bottom(self) -> Option<Expr<'a>>

The bottom attachment.

pub fn top(self) -> Option<Expr<'a>>

The top attachment.

pub fn primes(self) -> Option<MathPrimes<'a>>

Extract attached primes if present.

Trait Implementations

impl<'a> AstNode<'a> for MathAttach<'a>

fn from_untyped(node: &'a SyntaxNode) -> Option<Self>

Convert a node into its typed variant.

fn to_untyped(self) -> &'a SyntaxNode

A reference to the underlying syntax node.

fn placeholder() -> Self

A placeholder for this node type. If the underlying CST has syntax errors or did not come from the parser, the AST is not guaranteed to be valid. But instead of panicking in that case, we return placeholder nodes.

fn span(self) -> Span

The source code location.

impl<'a> Clone for MathAttach<'a>

fn clone(&self) -> MathAttach<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for MathAttach<'a>

impl<'a> Debug for MathAttach<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for MathAttach<'a>

impl<'a> Hash for MathAttach<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for MathAttach<'a>

fn eq(&self, other: &MathAttach<'a>) -> 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.
