[−][src]Struct abi_stable::prefix_type::WithMetadata_

#[repr(C)]

pub struct WithMetadata_<T, P> {
    pub _prefix_type_field_acc: FieldAccessibility,
    pub _prefix_type_layout: &'static PTStructLayout,
    pub original: T,
    // some fields omitted
}

Wraps a prefix-type,with extra metadata about field count and layout.

Can be converted to the PrefixTypeTrait::Prefix of T with the as_prefix method.

Fields

_prefix_type_field_acc: FieldAccessibility

A bit array,where the bit at field index represents whether a field is accessible.

_prefix_type_layout: &'static PTStructLayoutoriginal: T

Methods

impl<T, P> WithMetadata_<T, P>[src]

pub const fn new(metadata: WithMetadataFor<T, P>, value: T) -> Self[src]

Constructs Self with WithMetadata::new(PrefixTypeTrait::METADATA,value)

pub fn as_prefix(&self) -> &P[src]

Converts this WithMetadata<T,P> to a <prefix_struct> type.

pub const fn as_prefix_raw(&self) -> *const P[src]

Converts this WithMetadata<T,P> to a <prefix_struct> type. Use this if you need to implement nested vtables at compile-time.
