Struct TupleStructInfo

pub struct TupleStructInfo { /* private fields */ }

A container for compile-time tuple struct info.

Implementations

impl TupleStructInfo

pub fn new<T: Reflect + TypePath>(fields: &[UnnamedField]) -> Self

Create a new TupleStructInfo.

Arguments

• fields: The fields of this struct in the order they are defined

pub fn with_custom_attributes(self, custom_attributes: CustomAttributes) -> Self

Sets the custom attributes for this struct.

pub fn field_at(&self, index: usize) -> Option<&UnnamedField>

Get the field at the given index.

pub fn iter(&self) -> Iter<'_, UnnamedField>

Iterate over the fields of this struct.

pub fn field_len(&self) -> usize

The total number of fields in this struct.

pub fn ty(&self) -> &Type

The underlying Rust type.

pub fn type_id(&self) -> TypeId

The TypeId of this type.

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

The stable, full type path of this type.

Use type_path_table if you need access to the other methods on TypePath.

pub fn type_path_table(&self) -> &TypePathTable

A representation of the type path of this type.

Provides dynamic access to all methods on TypePath.

pub fn is<T: Any>(&self) -> bool

Check if the given type matches this one.

This only compares the TypeId of the types and does not verify they share the same TypePath (though it implies they do).

pub fn custom_attributes(&self) -> &CustomAttributes

Returns the custom attributes for this item.

pub fn get_attribute<T: Reflect>(&self) -> Option<&T>

Gets a custom attribute by type.

For dynamically accessing an attribute, see get_attribute_by_id.

pub fn get_attribute_by_id(&self, id: TypeId) -> Option<&dyn Reflect>

Gets a custom attribute by its TypeId.

This is the dynamic equivalent of get_attribute.

pub fn has_attribute<T: Reflect>(&self) -> bool

Returns true if this item has a custom attribute of the specified type.

For dynamically checking if an attribute exists, see has_attribute_by_id.

pub fn has_attribute_by_id(&self, id: TypeId) -> bool

Returns true if this item has a custom attribute with the specified TypeId.

This is the dynamic equivalent of has_attribute

pub fn generics(&self) -> &Generics

Gets the generic parameters for this type.

pub fn with_generics(self, generics: Generics) -> Self

Sets the generic parameters for this type.

Trait Implementations

Performs copy-assignment from source.

impl Debug for TupleStructInfo

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