Module prelude

Each module should have its own prelude, which:

• Adds preludes of upstream crates
• Exports types with specific-enough names which mean they can safely be used downstream.

The idea is that we can just include the current crate’s prelude and avoid messing around with tons of includes. This makes refactors easier, and makes integration into the node less painful.

Re-exports

• pub use crate::rust::prelude::*;
• pub use crate::iterators::*;

Macros

• assert_matches
  Attempts to be a replacement for assert!(matches!(...)) but with better error messages, and allowing further code on success.
• labelled_resolvable_using_resolvable_impl
• labelled_resolvable_with_identity_impl
• resolvable_with_identity_impl
• resolvable_with_try_into_impls

Structs

• ContextDisplayable

Traits

• ContextualDisplay
  This trait is used where context is required to correctly display a value.
• ContextualTryFrom
• ContextualTryInto
• LabelResolver
• LabelledResolvable
  LabelledResolvable is a marker trait, serving a few purposes:
• LabelledResolve
  This trait is intended to be used as an impl argument in helper methods, to accept a wider range of arguments.
• LabelledResolveFrom
  The inverse trait of LabelledResolve.
• Resolvable
  Resolvable is a marker trait, mainly to make resolution opt-in and to avoid polluting every type with a resolve method.
• Resolve
  This trait is intended to be used as an impl argument in helper methods, to accept a wider range of arguments.
• ResolveFrom
  The inverse trait of Resolve.

Functions

• combine
  Combines a u8 with a u8 slice.
• copy_u8_array
  Copies a slice to a fixed-sized array.
