Enum bones_lib::ecs::prelude::bones_schema::SchemaKind

pub enum SchemaKind {
    Struct(StructSchemaInfo),
    Vec(&'static Schema),
    Enum(EnumSchemaInfo),
    Map {
        key: &'static Schema,
        value: &'static Schema,
    },
    Box(&'static Schema),
    Primitive(Primitive),
}

A schema describes the data layout of a type, to enable dynamic access to the type’s data through a pointer.

Variants

Struct(StructSchemaInfo)

The type represents a struct.

Vec(&'static Schema)

Type represents a SchemaVec, where each item in the vec has the contained [Schema].

The scripting solution must facilitate a way for scripts to access data in the Vec if it is to be readable/modifyable from scripts.

Enum(EnumSchemaInfo)

Type represents an enum, which in the C layout is called a tagged union.

Map

Type represents a SchemaMap.

Fields

key: &'static Schema

The schema of the key type.

value: &'static Schema

The schema of the value type.

Box(&'static Schema)

The represents a SchemaBox with given type inside.

Primitive(Primitive)

The type represents a primitive value.

Implementations

impl SchemaKind

pub fn as_primitive(&self) -> Option<&Primitive>

Get the primitive, if this is a primitive.

pub fn as_struct(&self) -> Option<&StructSchemaInfo>

Get the struct, if this is a struct.

pub fn as_enum(&self) -> Option<&EnumSchemaInfo>

Get the enum, if this is a enum.

pub fn as_vec(&self) -> Option<&'static Schema>

Get the schema of the items in the vector, if this is a vector.

impl SchemaKind

pub fn compute_layout_info(&self) -> SchemaLayoutInfo<'_>

Calculate the layout of the type represented by the schema.

Usually you don’t need to call this and should use the static, cached layout and field offsets from [Schema::layout()] and [Schema::field_offsets()].

pub fn has_opaque(&self) -> bool

Recursively checks whether or not the schema contains any Opaque primitives.

Trait Implementations

impl Clone for SchemaKind

fn clone(&self) -> SchemaKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaKind

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

Formats the value using the given formatter.
