Implementations

impl Type

pub fn size(&self) -> Option<ValSize>

Indicates how many bytes a type requires to be stored in memory.

Recursive types yield the sum of their sub-type sizes, unsized types panic, and functions do not have a size, so they produce None.

Panics

Panics if the type is an instance of Type::Option, Type::String, or Type::Bytes because their size is undetermined.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl Display for Type

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

Formats the value using the given formatter.

impl From<ConcreteValueType> for Type

fn from(ty: ConcreteValueType) -> Type

Performs the conversion.

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 ==.
