Enum AttributeValue

pub enum AttributeValue {
    Shorthand(Ident),
    AttrLiteral(HotLiteral),
    EventTokens(PartialClosure),
    IfExpr(IfAttributeValue),
    AttrExpr(PartialExpr),
}

Variants

Shorthand(Ident)

Just a regular shorthand attribute - an ident. Makes our parsing a bit more opaque. attribute,

AttrLiteral(HotLiteral)

Any attribute that’s a literal. These get hotreloading super powers

attribute: “value” attribute: bool, attribute: 1,

EventTokens(PartialClosure)

A series of tokens that represent an event handler

We use a special type here so we can get autocomplete in the closure using partial expansion. We also do some extra wrapping for improved type hinting since rust sometimes has trouble with generics and closures.

IfExpr(IfAttributeValue)

Conditional expression

attribute: if bool { “value” } else if bool { “other value” } else { “default value” }

Currently these don’t get hotreloading super powers, but they could, depending on how far we want to go with it

AttrExpr(PartialExpr)

attribute: some_expr attribute: {some_expr} ?

Implementations

impl AttributeValue

pub fn span(&self) -> Span

Trait Implementations

impl Clone for AttributeValue

fn clone(&self) -> AttributeValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeValue

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

Formats the value using the given formatter.

impl Hash for AttributeValue

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 Parse for AttributeValue

fn parse(content: ParseStream<'_>) -> Result<Self>

impl PartialEq for AttributeValue

fn eq(&self, other: &AttributeValue) -> 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 ToTokens for AttributeValue

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.

impl Eq for AttributeValue
