Module abi_stable::prefix_type

Types,traits,and functions used by prefix-types.

Structs

• PTStructLayout
  Represents the layout of a prefix-type,for use in error messages.
• PrefixRef
  A reference to a prefix type.
• WithMetadata_
  Wraps a type along with its prefix-type-related metadata, so that it can be converted to its prefix.

Enums

• IsAccessible
  Whether a field is accessible.
• IsConditional
  Whether a field is conditional, whether it has a #[sabi(accessible_if = expression)] helper attribute or not.

Traits

• PrefixRefTrait
  Marker trait for pointers to prefix field structs.
• PrefixTypeTrait
  For types deriving StableAbi with #[sabi(kind(Prefix(..)))].

Functions

• panic_on_missing_field_ty
  Used to panic with an error message informing the user that a field is expected to be on the T type when it’s not.
• panic_on_missing_fieldname
  Used to panic with an error message informing the user that a field is expected to be on the T type when it’s not.

Type Aliases

• FieldAccessibility
  An array with whether the ith field of a prefix-type is accessible through its accessor method.
• FieldConditionality
  An array with whether the ith field in the prefix of a prefix-type is conditional,which means whether it has the #[sabi(accessible_if = expression)] attribute applied to it.
• WithMetadata
  Alias for WithMetadata_ that defaults to passing <T as PrefixTypeTrait>::PrefixFields as the second type parameter.
