Struct bones_framework::asset::SchemaRefMut

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

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

Implementations

impl<'pointer> SchemaRefMut<'pointer>

pub unsafe fn cast_mut_unchecked<T>(&mut self) -> &mut T

Cast this pointer to a mutable reference.

Safety

You must uphold all safety requirements of NonNull::as_mut().

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

Cast this pointer to a mutable reference.

Safety

You must uphold all safety requirements of NonNull::as_mut().

pub fn cast_mut<T>(&mut self) -> &mut Twhere T: HasSchema + 'static,

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_mut<T>(&mut self) -> Result<&mut T, SchemaMismatchError>where T: HasSchema,

Cast this pointer to a mutable 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 cast_into_mut<T>(self) -> &'pointer mut Twhere T: HasSchema,

Cast this pointer to a mutable reference to a type with a matching [Schema]. This is different than try_cast because it consumes the SchemaRefMut and allows you to, for instance, pass it out of a mapping operation without keeping a reference to the old SchemaRefMut.

Panics

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

pub fn try_cast_into_mut<T>( self ) -> Result<&'pointer mut T, SchemaMismatchError>where T: HasSchema,

Cast this pointer to a mutable reference to a type with a matching [Schema]. This is different than try_cast because it consumes the SchemaRefMut and allows you to, for instance, pass it out of a mapping operation without keeping a reference to the old SchemaRefMut.

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 mut T) -> SchemaRefMut<'pointer>where T: HasSchema,

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

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

Create a new SchemaRefMut 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 reads and writes of the pointee type.
• The pointer must be valid for the full lifetime of this SchemaRef.

pub fn into_map(self) -> Result<&'pointer mut SchemaMap, SchemaRefMut<'pointer>>

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

pub fn into_vec(self) -> Result<&'pointer mut SchemaVec, SchemaRefMut<'pointer>>

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

pub fn into_box(self) -> Result<SchemaRefMut<'pointer>, SchemaRefMut<'pointer>>

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

pub fn into_access_mut(self) -> SchemaRefMutAccess<'pointer>

Convert into an accessor for the inner data.

pub fn access_mut(&mut self) -> SchemaRefMutAccess<'_>

Get a mutable access helper to this reference.

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

Get the raw 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_ref(&self) -> SchemaRef<'_>

Borrow this SchemaRefMut as a SchemaRef.

pub fn reborrow(&mut self) -> SchemaRefMut<'_>

Convert a borrowed SchemaRefMut to an owned SchemaRefMut with a lifetime matching That of the borrow.

pub fn field<'a, I>(&mut self, field_idx: I) -> Option<SchemaRefMut<'_>>where I: Into<FieldIdx<'a>>,

Get the reference to a field.

pub fn field_path<'a, I>(&mut self, path: I) -> Option<SchemaRefMut<'_>>where I: IntoIterator<Item = FieldIdx<'a>>,

Get the field pointed to by the given path.

pub fn into_field_path<'a, I>(self, path: I) -> Option<SchemaRefMut<'pointer>>where I: IntoIterator<Item = FieldIdx<'a>>,

Get the field pointed to by the given path.

pub fn into_field<'a, I>( self, field_idx: I ) -> Result<SchemaRefMut<'pointer>, SchemaRefMut<'pointer>>where I: Into<FieldIdx<'a>>,

Get the reference to a field.

pub fn write(&mut self, other: SchemaRef<'_>) -> Result<(), SchemaMismatchError>

Clone other and write it’s data to self. Panics if this schema doesn’t support cloning.

Trait Implementations

impl<'pointer> Debug for SchemaRefMut<'pointer>

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

Formats the value using the given formatter.

impl<'a, 'de> DeserializeSeed<'de> for SchemaRefMut<'a>

type Value = ()

fn deserialize<D>( self, deserializer: D ) -> Result<<SchemaRefMut<'a> as DeserializeSeed<'de>>::Value, <D as Deserializer<'de>>::Error>where D: Deserializer<'de>,

Equivalent to the more common Deserialize::deserialize method, except with some initial piece of data (the seed) passed in.
