Struct tetsy_scale_info::MetaType

pub struct MetaType { /* fields omitted */ }

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: ?Sized>() -> Self where
    T: TypeInfo + 'static, 

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

pub fn type_info(&self) -> Type<MetaForm>

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.

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

Performs copy-assignment from source.

impl Copy for MetaType

impl Debug for MetaType

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

Formats the value using the given formatter.

impl Eq for MetaType

impl Hash for MetaType

fn hash<H>(&self, state: &mut H) where
    H: Hasher, 

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for MetaType

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<MetaType> for MetaType

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

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

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<MetaType> for MetaType

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

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

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

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

#[must_use]pub fn le(&self, other: &Rhs) -> bool

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

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

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

#[must_use]pub fn ge(&self, other: &Rhs) -> bool

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