Struct ExprBlock

#[non_exhaustive]
pub struct ExprBlock {
    pub attributes: Vec<Attribute>,
    pub async_token: Option<Async>,
    pub const_token: Option<Const>,
    pub move_token: Option<Move>,
    pub label: Option<(Label, Colon)>,
    pub block: Block,
}

A block expression.

• <block>.
• async <block>.
• const <block>.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

attributes: Vec<Attribute>

The attributes for the block.

async_token: Option<Async>

The optional async token.

const_token: Option<Const>

The optional const token.

move_token: Option<Move>

The optional move token.

label: Option<(Label, Colon)>

An optional label for the block.

block: Block

The close brace.

Trait Implementations

impl Debug for ExprBlock

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

Formats the value using the given formatter.

impl OptionSpanned for ExprBlock

fn option_span(&self) -> Option<Span>

Get the optional span of the type.

impl Parse for ExprBlock

fn parse(p: &mut Parser<'_>) -> Result<Self>

Parse the current item from the parser.

impl PartialEq for ExprBlock

fn eq(&self, other: &ExprBlock) -> 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 Spanned for ExprBlock

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for ExprBlock

fn to_tokens( &self, context: &mut MacroContext<'_, '_, '_>, stream: &mut TokenStream, ) -> Result<()>

Turn the current item into tokens.

impl TryClone for ExprBlock

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.

impl Eq for ExprBlock

impl StructuralPartialEq for ExprBlock
