Struct Delimited 

pub struct Delimited<T, Span> {
    pub span: Span,
    pub inner: T,
}

A value enclosed by delimiters (e.g., brackets, braces, parentheses).

Stores the combined span of the delimiters and the inner content. Use this to represent constructs like [items], {block}, or (expr).

Type Parameters

• T: The inner content type
• Span: The span type for source positions

Example

// Parse: [1, 2, 3]
let bracket = bracket!(inner in stream);
// `inner` is a TokenStream of "1, 2, 3"
// `bracket` is Delimited with span covering "[...]"
let items: Punctuated<Expr, Comma> = inner.parse()?;

Fields

span: Span

The span covering the entire delimited region (including delimiters).

inner: T

The inner content between the delimiters.

Trait Implementations

impl<T: Clone, Span: Clone> Clone for Delimited<T, Span>

fn clone(&self) -> Delimited<T, Span>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug, Span: Debug> Debug for Delimited<T, Span>

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

Formats the value using the given formatter.

impl<T, Span> Deref for Delimited<T, Span>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T, Span> DerefMut for Delimited<T, Span>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T: PartialEq, Span: PartialEq> PartialEq for Delimited<T, Span>

fn eq(&self, other: &Delimited<T, Span>) -> 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.
