[][src]Struct proc_macro_error::single::MacroError

pub struct MacroError { /* fields omitted */ }

An single error message in a proc macro with span info attached.

Methods

impl MacroError[src]

pub fn new(span: Span, msg: String) -> Self[src]

Create an error with the span and message provided.

pub fn call_site(msg: String) -> Self[src]

A shortcut for MacroError::new(Span::call_site(), message)

pub fn set_span(&mut self, span: Span) -> Span[src]

Replace the span info with span. Returns old span.

pub fn span(&self) -> Span[src]

Get the span contained.

pub fn abort(self) -> ![src]

Abort the proc-macro's execution and show the error.

You're not supposed to use this function directly. Use abort! instead.
