Expand description

Represents all the different high-level types that can be used in a component interface. At this level we identify user-defined types by name, without knowing any details of their internal structure apart from what type of thing they are (record, enum, etc).

Implementations§

§

impl Type

pub fn iter_types(&self) -> Box<dyn Iterator<Item = &Type> + '_, Global>

Trait Implementations§

§

impl AsType for Type

§

fn as_type(&self) -> Type

§

impl Checksum for Type

§

fn checksum<__H>(&self, state: &mut __H)where __H: Hasher,

§

impl Clone for Type

§

fn clone(&self) -> Type

Returns a copy of the value. Read more
1.0.0 · source§

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

Performs copy-assignment from source. Read more
§

impl Debug for Type

§

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

Formats the value using the given formatter. Read more
source§

impl From<&&Type> for FfiType

source§

fn from(ty: &&Type) -> Self

Converts to this type from the input type.
source§

impl From<&Type> for FfiType

When passing data across the FFI, each Type value will be lowered into a corresponding FfiType value. This conversion tells you which one.

Note that the conversion is one-way - given an FfiType, it is not in general possible to tell what the corresponding Type is that it’s being used to represent.

source§

fn from(t: &Type) -> FfiType

Converts to this type from the input type.
source§

impl From<Type> for FfiType

source§

fn from(ty: Type) -> Self

Converts to this type from the input type.
§

impl Ord for Type

§

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

This method returns an Ordering between self and other. Read more
1.21.0 · source§

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

Compares and returns the maximum of two values. Read more
1.21.0 · source§

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

§

impl PartialEq<Type> for Type

§

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

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