Enum bones_lib::ecs::prelude::bones_schema::ptr::SchemaRefAccess

pub enum SchemaRefAccess<'a> {
    Struct(StructRefAccess<'a>),
    Vec(SchemaVecAccess<'a>),
    Enum(EnumRefAccess<'a>),
    Map(SchemaMapAccess<'a>),
    Primitive(PrimitiveRef<'a>),
}

Helper for accessing the inner data of a schema ref at runtime.

Variants

Struct(StructRefAccess<'a>)

Access a struct.

Vec(SchemaVecAccess<'a>)

Access a vec.

Enum(EnumRefAccess<'a>)

Access an enum.

Map(SchemaMapAccess<'a>)

Access a map.

Primitive(PrimitiveRef<'a>)

Access a struct.

Implementations

impl<'ptr> SchemaRefAccess<'ptr>

pub fn new(value: SchemaRef<'_>) -> SchemaRefAccess<'_>

Create a new SchemaRefAccess for the given SchemaRef.

This will create a new independent SchemaRefAccess that may be used even after the original SchemaRef is dropped ( but not beyond the safe lifetime of the original schema ref ).

pub fn new_borrowed<'borrow>( value: &'borrow SchemaRef<'_>, ) -> SchemaRefAccess<'borrow>

Create a new SchemaRefAccess for the given SchemaRef that borrows the original SchemaRef.

This is subtly different from SchemaRefAccess::new() because it requires that it hold a borrow to the original schema ref it was created from. This is specifically useful becuse it lets you create a SchemaRefAccess from a refeence to a schema ref, which is required when accessing a schema ref that is behind an atomic resource borrow, for example.

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

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

Get field with the given index.

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

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

Get the field pointed to by the given path.

pub fn into_schema_ref(self) -> SchemaRef<'ptr>

Borrow this SchemaRefMutAccess as a SchemaRefAccess.

Trait Implementations

impl<'a> Clone for SchemaRefAccess<'a>

fn clone(&self) -> SchemaRefAccess<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaRefAccess<'_>

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

Formats the value using the given formatter.
