Enum Extensibility 

pub enum Extensibility {
    Final,
    Appendable,
    Mutable,
}

Struct extensibility. DDS-XTypes 1.3 §7.2.4.4.

Ordered so that it can sit in a layout key, which the plan cache keys on: the order is the declaration order and carries no meaning of its own.

Variants

Final

@final — no evolution.

Appendable

@appendable — members may be appended.

Mutable

@mutable — members carry ids and may be reordered.

Implementations

impl Extensibility

pub const ALL: [Self; 3]

Every extensibility XTypes defines.

pub const fn as_str(self) -> &'static str

Source spelling.

pub fn parse(value: &str) -> Option<Self>

Parse a configuration value, in the spelling Self::as_str produces.

An unknown value returns None rather than falling back to a default: the setting decides whether a DHEADER goes on the wire, and a typo in it must be loud.

Trait Implementations

impl Clone for Extensibility

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Extensibility

impl Debug for Extensibility

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

Formats the value using the given formatter.

impl Eq for Extensibility

impl Hash for Extensibility

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 Extensibility

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Extensibility

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Extensibility

fn partial_cmp(&self, other: &Self) -> 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.
