Struct Position 

pub struct Position {
    pub is_first: bool,
    pub is_last: bool,
}

The first component of the value yielded by WithPosition. Indicates the position of this element in the iterator results.

See .with_position() for more information.

Fields

is_first: bool

This is the initial element (also true if there’s exactly one element)

is_last: bool

This is the final element (also true if there’s exactly one element)

Implementations

impl Position

pub fn is_exactly_one(self) -> bool

This is the first and the last element at the same time, and there are no more elements

pub fn is_middle(self) -> bool

This is neither first nor last element, and there will be more elements

pub fn is_first(self) -> bool

This is the initial element (also true if there’s exactly one element)

pub fn is_last(self) -> bool

This is the final element (also true if there’s exactly one element)

Trait Implementations

impl Clone for Position

fn clone(&self) -> Position

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Position

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

Formats the value using the given formatter.

impl PartialEq for Position

fn eq(&self, other: &Position) -> 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 Copy for Position

impl Eq for Position

impl StructuralPartialEq for Position
