Struct bones_framework::asset::prelude::SchemaRef

pub struct SchemaRef<'pointer> { /* private fields */ }

An untyped reference that knows the [Schema] of the pointee and that can be cast to a matching type.

Implementations

impl<'pointer> SchemaRef<'pointer>

pub unsafe fn cast_unchecked<T>(&self) -> &T

Unsafely cast this pointer to a specifc Rust type.

Safety

All of the safety requirements of NonNull::as_ref() must be met.

pub unsafe fn cast_into_unchecked<T>(self) -> &'pointer T

Unsafely cast this pointer to a specifc Rust type.

Safety

All of the safety requirements of NonNull::as_ref() must be met.

pub fn cast<T>(&self) -> &'pointer T

where T: HasSchema,

Cast this pointer to a reference to a type with a matching [Schema].

Panics

Panics if the schema of the pointer does not match that of the type you are casting to.

pub fn try_cast<T>(&self) -> Result<&'pointer T, SchemaMismatchError>

where T: HasSchema,

Cast this pointer to a reference to a type with a matching [Schema].

Errors

Errors if the schema of the pointer does not match that of the type you are casting to.

pub fn new<T>(v: &'pointer T) -> SchemaRef<'pointer>

where T: HasSchema,

Create a new SchemaRef from a reference to a type that implements HasSchema.

pub unsafe fn from_ptr_schema( ptr: *const c_void, schema: &'static Schema, ) -> SchemaRef<'pointer>

Create a new SchemaRef from a raw pointer and it’s schema.

Safety

• The pointee of ptr must be accurately described by the given schema.
• inner must have correct provenance to allow read of the pointee type.
• The pointer must be valid for the full lifetime of this SchemaRef.

pub fn as_ptr(&self) -> *const c_void

Get the pointer.

pub fn schema(&self) -> &'static Schema

Get the [Schema] for the pointer.

pub fn hash(&self) -> Option<u64>

Get the hash of this schema box, if supported.

pub fn as_map(&self) -> Option<&'pointer SchemaMap>

Borrow the schema ref as a SchemaMap if it is one.

pub fn as_vec(&self) -> Option<&'pointer SchemaVec>

Borrow the schema ref as a SchemaVec if it is one.

pub fn as_box(&self) -> Option<SchemaRef<'pointer>>

Borrow the schema ref as a SchemaBox if it is one.

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

Debug format the value stored in the schema box.

This is used in the display and debug implementations.

pub fn access(self) -> SchemaRefAccess<'pointer>

Get a helper to access the inner data.

pub fn field<'a, I>(self, field_idx: I) -> Option<SchemaRef<'pointer>>

where I: Into<FieldIdx<'a>>,

Get the reference to a field.

pub fn field_path<'a, I>(self, path: I) -> Option<SchemaRef<'pointer>>

where I: IntoIterator<Item = FieldIdx<'a>>,

Get the field pointed to by the given path.

pub fn clone_into_box(&self) -> SchemaBox

Clone this schema ref into a new box.
