Struct Output 

pub struct Output { /* private fields */ }

The result of rendering an element or expanding a template.

Holds both the generated token output and any accumulated diagnostics. Implements ToTokens by emitting the tokens followed by any diagnostic compiler messages, preserving the same behavior as the previous TokenStream return type.

Implementations

impl Output

pub fn new() -> OutputBuilder

Creates a new OutputBuilder.

pub fn tokens(&self) -> &TokenStream

Returns the generated token output.

pub fn diagnostic(&self) -> &Diagnostic

Returns the accumulated diagnostic.

pub fn into_parts(self) -> (TokenStream, Diagnostic)

Consumes the output and returns its tokens and diagnostic.

pub fn is_error(&self) -> bool

Returns true if the diagnostic contains an error.

Methods from Deref<Target = TokenStream>

pub fn is_empty(&self) -> bool

Checks if this TokenStream is empty.
