Struct PopRight 

pub struct PopRight;

Removes the last token tree from the stream (useful for trailing commas or other garbage).

Arguments

This does not take any argument.

Example

[< a b c >]:pop_right ->a b

Trait Implementations

impl Clone for PopRight

fn clone(&self) -> PopRight

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PopRight

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

Formats the value using the given formatter.

impl Default for PopRight

fn default() -> PopRight

Returns the “default value” for a type.

impl Hash for PopRight

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PopRight

fn cmp(&self, other: &PopRight) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PopRight

fn eq(&self, other: &PopRight) -> 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.

impl PartialOrd for PopRight

fn partial_cmp(&self, other: &PopRight) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Pass for PopRight

type Argument = Nothing

The argument type used by this pass.

fn through( &mut self, input: TokenStream, _: Self::Argument, ) -> Result<TokenStream>

Pass-through an input [token stream] with an appropiate source-parsable argument.
