Expand description

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

Fields

§key: &'static Schema

The schema of the key type.

§value: &'static Schema

The schema of the value type.

Type represents a SchemaMap.

§

Box(&'static Schema)

The represents a SchemaBox with given type inside.

§

Primitive(Primitive)

The type represents a primitive value.

Implementations§

source§

impl SchemaKind

source

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

Get the primitive, if this is a primitive.

source

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

Get the struct, if this is a struct.

source

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

Get the enum, if this is a enum.

source

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

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

source§

impl SchemaKind

source

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().

source

pub fn has_opaque(&self) -> bool

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