Implementations

impl OptionalUint32

pub fn ordinal(&self) -> u64

pub fn is_unknown(&self) -> bool

👎Deprecated: Strict unions should not use is_unknown

Trait Implementations

impl Autonull for OptionalUint32

fn naturally_nullable(_context: &Context) -> bool

Returns true if the type is naturally able to be nullable.

impl Clone for OptionalUint32

fn clone(&self) -> OptionalUint32

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OptionalUint32

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

Formats the value using the given formatter.

impl Decodable for OptionalUint32

fn new_empty() -> Self

Creates a new value of this type with an “empty” representation.

fn decode(&mut self, decoder: &mut Decoder<'_>, offset: usize) -> Result<()>

Decodes an object of this type from the decoder’s buffers into self. Callers must ensure that offset is a multiple of Layout::inline_align, and that decoder.buf has room for reading Layout::inline_size bytes at offset.

impl Encodable for OptionalUint32

fn encode( &mut self, encoder: &mut Encoder<'_, '_>, offset: usize, recursion_depth: usize ) -> Result<()>

Encode the object into the buffer. Any handles stored in the object are swapped for Handle::INVALID. Callers must ensure that offset is a multiple of Layout::inline_align, and that encoder.buf has room for writing Layout::inline_size bytes at offset.

impl Hash for OptionalUint32

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 Layout for OptionalUint32

fn inline_align(_context: &Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(context: &Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for the type’s alignment. Must be a multiple of inline_align.

fn supports_simple_copy() -> boolwhere Self: Sized,

Returns true iff the type can be encoded or decoded via simple copy.

impl Ord for OptionalUint32

fn cmp(&self, other: &OptionalUint32) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<OptionalUint32> for OptionalUint32

fn eq(&self, other: &OptionalUint32) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<OptionalUint32> for OptionalUint32

fn partial_cmp(&self, other: &OptionalUint32) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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