Struct gstd::util::MetaType

pub struct MetaType { /* private fields */ }

A metatype abstraction.

Allows to store compile-time type information at runtime. This again allows to derive type ID and type definition from it.

This needs a conversion to another representation of types in order to be serializable.

Implementations

impl MetaType

pub fn new<T>() -> MetaType

where T: TypeInfo + 'static + ?Sized,

Creates a new meta type from the given compile-time known type.

pub fn type_info(&self) -> Type

Returns the meta type information.

pub fn type_id(&self) -> TypeId

Returns the type identifier provided by core::any.

Trait Implementations

impl Clone for MetaType

fn clone(&self) -> MetaType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetaType

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

Formats the value using the given formatter.

impl Hash for MetaType

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 MetaType

fn cmp(&self, other: &MetaType) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for MetaType

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

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