Struct Descriptor 

pub struct Descriptor<Id> { /* private fields */ }

Describes a type.

The static properties of a type are exposed here.

Equality between Descriptor instances is based only on the Id type.

Implementations

impl<Id: PartialEq> Descriptor<Id>

pub const fn new<T: Inspect<Id>>() -> Self

Create a Descriptor for type T.

This function can be used in const contexts.

pub fn is_type<T: Inspect<Id>>(&self) -> bool

Check if the Descriptor is for the type T.

If this method returns true then the descriptor was created for type T.

pub fn id(&self) -> Id

Get the ID for the type.

pub fn type_name(&self) -> &'static str

Get the name of the type.

This uses std::any::type_name() so should only be used for diagnostics.

pub const fn size(&self) -> usize

Size of the type in bytes.

pub const fn alignment(&self) -> usize

Alignment of the type in bytes.

pub const fn layout_can_store<L: IsLayout>(&self) -> bool

Alignment of the type in bytes.

Trait Implementations

impl<Id> Clone for Descriptor<Id>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Id: PartialEq> Debug for Descriptor<Id>

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

Formats the value using the given formatter.

impl<Id: PartialEq + Hash> Hash for Descriptor<Id>

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<Id: PartialEq + Ord> Ord for Descriptor<Id>

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.

impl<Id: PartialEq> PartialEq for Descriptor<Id>

fn eq(&self, other: &Self) -> 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<Id: PartialEq + PartialOrd> PartialOrd for Descriptor<Id>

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.
