Struct Terminated 

pub struct Terminated<T, P>(/* private fields */);

A punctuated sequence with required trailing separator.

Use this for statement-like constructs where each item must end with punctuation, such as use statements: use foo; use bar;.

Type Parameters

• T: The value type (e.g., statement)
• P: The punctuation/separator type (e.g., semicolon token)

Implementations

impl<T, P> Terminated<T, P>

pub const POLICY: TrailingPolicy = TrailingPolicy::Required

The trailing punctuation policy for this type.

pub fn new() -> Terminated<T, P>

Creates a new empty sequence.

pub fn with_capacity(capacity: usize) -> Terminated<T, P>

Creates a new sequence with pre-allocated capacity.

pub fn push_value(&mut self, value: T)

Pushes a value onto the sequence.

pub fn push_punct(&mut self, punct: P)

Attaches punctuation to the last value.

pub fn trailing_punct(&self) -> bool

Returns whether the sequence has trailing punctuation.

The return value depends on the wrapper type’s policy:

• Punctuated: delegates to inner storage
• Terminated: always true
• Separated: always false

pub fn into_inner(self) -> PunctuatedInner<T, P>

Consumes the wrapper and returns the inner storage.
