pub struct SchemaBox { /* private fields */ }
Expand description
A owning, type-erased Box
-like container for types with a [Schema
].
Implementations§
source§impl SchemaBox
impl SchemaBox
sourcepub fn cast_into<T>(self) -> Twhere
T: HasSchema,
pub fn cast_into<T>(self) -> Twhere
T: HasSchema,
Cast this box to it’s inner type and return it.
§Panics
Panics if the schema of the box does not match that of the type you are casting to.
sourcepub fn try_cast_into<T>(self) -> Result<T, SchemaMismatchError>where
T: HasSchema,
pub fn try_cast_into<T>(self) -> Result<T, SchemaMismatchError>where
T: HasSchema,
Cast this box to it’s inner type and return it.
§Errors
Errors if the schema of the box does not match that of the type you are casting to.
sourcepub unsafe fn cast_into_unchecked<T>(self) -> Twhere
T: HasSchema,
pub unsafe fn cast_into_unchecked<T>(self) -> Twhere
T: HasSchema,
Unsafely convert this box into an owned T.
§Safety
- The schema of type T must equal that of this box.
sourcepub fn cast_ref<T>(&self) -> &Twhere
T: HasSchema,
pub fn cast_ref<T>(&self) -> &Twhere
T: HasSchema,
Cast this box to a reference to a type with a representative [Schema
].
§Panics
Panics if the schema of the box does not match that of the type you are casting to.
sourcepub fn try_cast_ref<T>(&self) -> Result<&T, SchemaMismatchError>where
T: HasSchema,
pub fn try_cast_ref<T>(&self) -> Result<&T, SchemaMismatchError>where
T: HasSchema,
Cast this box to a reference to a type with a representative [Schema
].
§Errors
Errors if the schema of the box does not match that of the type you are casting to.
sourcepub fn cast_mut<T>(&mut self) -> &mut Twhere
T: HasSchema,
pub fn cast_mut<T>(&mut self) -> &mut Twhere
T: HasSchema,
Cast this box to a mutable reference to a type with a representing [Schema
].
§Panics
Panics if the schema of the box does not match that of the type you are casting to.
sourcepub fn try_cast_mut<T>(&mut self) -> Result<&mut T, SchemaMismatchError>where
T: HasSchema,
pub fn try_cast_mut<T>(&mut self) -> Result<&mut T, SchemaMismatchError>where
T: HasSchema,
Cast this box to a mutable reference to a type with a representing [Schema
].
§Errors
Errors if the schema of the box does not match that of the type you are casting to.
sourcepub fn as_mut(&mut self) -> SchemaRefMut<'_>
pub fn as_mut(&mut self) -> SchemaRefMut<'_>
Borrow this box as a SchemaRefMut
.
sourcepub unsafe fn uninitialized(schema: &'static Schema) -> SchemaBox
pub unsafe fn uninitialized(schema: &'static Schema) -> SchemaBox
sourcepub fn default(schema: &'static Schema) -> SchemaBox
pub fn default(schema: &'static Schema) -> SchemaBox
Create a new SchemaBox
for a type with a [Schema
] that has a
SchemaData::default_fn
.
§Panics
Panics if the passed in schema doesn’t have a default_fn
.
sourcepub unsafe fn from_raw_parts(
ptr: NonNull<c_void>,
schema: &'static Schema,
) -> SchemaBox
pub unsafe fn from_raw_parts( ptr: NonNull<c_void>, schema: &'static Schema, ) -> SchemaBox
