    pub path: Path,
    pub bang: Bang,
    pub open: Token,
    pub stream: TokenStream,

}

A function call <expr>!(<args>).

Fields

id: Option<Id>

Opaque identifier for macro call. Use to store reference to internally expanded macros.

attributes: Vec<Attribute>

Attributes associated with macro call.

path: Path

The expression being called over.

bang: Bang

Bang operator !.

open: Token

Opening token.

stream: TokenStream

The tokens provided to the macro.

close: Token

Closing token.

Implementations

impl MacroCall

pub fn needs_semi(&self) -> bool

Test if macro needs semi or not.

pub fn adjust_expr_semi(&self, expr: Expr) -> Expr

Wrap the expression into an expression that matches the semi convention of the macro call.

pub fn stream_span(&self) -> Span

The span of the token stream.

pub fn parse_with_meta_path(
    parser: &mut Parser<'_>,
    attributes: Vec<Attribute>,
    path: Path
) -> Result<Self, ParseError>

Parse with an expression.
