Struct FieldIndex 

pub struct FieldIndex(pub u32);

The index of a field (whether of a struct/enum variant, tuple, or closure). For a struct/enum it converts from and to the LocalFieldId, for a tuple or closure it’s simply the index.

Tuple Fields

0: u32

Implementations

impl FieldIndex

pub fn to_local_field_id(self) -> Idx<FieldData>

Trait Implementations

impl Clone for FieldIndex

fn clone(&self) -> FieldIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldIndex

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

Formats the value using the given formatter.

impl From<Idx<FieldData>> for FieldIndex

fn from(value: Idx<FieldData>) -> FieldIndex

Converts to this type from the input type.

impl Hash for FieldIndex

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

where __H: Hasher,

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 FieldIndex

fn cmp(&self, other: &FieldIndex) -> 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 FieldIndex

fn eq(&self, other: &FieldIndex) -> 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 FieldIndex

fn partial_cmp(&self, other: &FieldIndex) -> 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 Update for FieldIndex

unsafe fn maybe_update( old_pointer_: *mut FieldIndex, new_value_: FieldIndex, ) -> bool

Returns

impl Copy for FieldIndex

impl Eq for FieldIndex
