Enum ParseMode

pub enum ParseMode {
    Named(Span),
    Unnamed,
}

The context a meta item parser is operating in.

Variants

Named(Span)

Named context, corresponding to syn::FieldsNamed.

Contains the Span of the name tokens.

Unnamed

Unnamed context, corresponding to syn::FieldsUnnamed.

Implementations

impl ParseMode

pub fn to_named(&self, input: ParseStream<'_>) -> Self

Converts self to a Self::Named.

If self is Unnamed, uses the Span from input.

pub fn named_span(&self) -> Option<Span>

Gets the stored Span.

If self is Unnamed, returns None.

pub fn to_span(&self, input: ParseStream<'_>) -> Span

Gets the stored Span.

If self is Unnamed, returns the Span from input.

pub fn to_full_span<'s, S: Borrow<ParseBuffer<'s>>>(&self, inputs: &[S]) -> Span

Gets the stored Span.

If self is Unnamed, returns inputs_span(inputs).
