Crate intid 

Defines the IntegerId trait, for types that can be identified by an integer value.

This crate simply re-exports all types from the intid_core crate. This reduces compile times by allowing crates to avoid proc macros. It is inspired by the separation between serde_core and serde introduced in serde-rs/serde#2608.

Note that many of the use-cases of a derive(...) macro can be achieved just as well (or better) using the intid::define_newtype_id declarative macro.

Modules

trusted

Since IntegerId and IntegerIdContiguous are safe traits, it is not possible for unsafe code to rely on them for correctness.

uint

Defines the UnsignedPrimInt trait and its generic operations.

utils

Miscellaneous utilities relating to the IntegerId trait.

Macros

define_newtype_counter

Defines a new type IntegerIdCounter, which wraps another IntegerIdCounter

define_newtype_id

Defines a newtype IntegerId, which wraps another IntegerId.

impl_newtype_id_body

Implements the body of the IntegerId trait for a newtype struct.

Traits

EnumId

An IntegerId which are limited to small set of indexes.

EquivalentId

A type that can be for lookup as an IntegerId.

IntegerId

An identifier which can be sensibly converted to/from an unsigned integer value.

IntegerIdContiguous

Indicates that an id occupies contiguous range of contiguous values, and all values between IntegerId::MIN_ID and IntegerId::MAX_ID are valid.

IntegerIdCounter

An IntegerId that can be sensibly used as a counter, starting at a Self::START value and being incremented from there.

UnsignedPrimInt

An unsigned primitive integer.

Derive Macros

EnumId

Implements EnumId for a C-like enum, enabling use of the EnumMap and EnumSet collections.

IntegerId

Implements IntegerId for a newtype struct or C-like enum.

IntegerIdContiguous

Implements IntegerIdContiguous for a newtype struct.

IntegerIdCounter

Implements IntegerIdCounter for a newtype struct.
