Modules

• arbitrary 🔒
  Support for configurable generation of arbitrary nix values
• attrs 🔒
  This module implements Nix attribute sets. They have flexible backing implementations, as they are used in very versatile use-cases that are all exposed the same way in the language surface.
• builtin 🔒
  This module implements the runtime representation of a Nix builtin.
• function 🔒
  This module implements the runtime representation of functions.
• json 🔒
• list 🔒
  This module implements Nix lists.
• path 🔒
• string 🔒
  This module implements Nix language strings.
• thunk 🔒
  This module implements the runtime representation of Thunks.

Macros

• gen_cast 🔒
  Generate an as_* method returning a reference to the expected type, or a type error. This only works for types that implement Copy, as returning a reference to an inner thunk value is not possible. Generate an as_*/to_* accessor method that returns either the expected type, or a type error.
• gen_cast_mut 🔒
  Generate an as_*_mut/to_*_mut accessor method that returns either the expected type, or a type error.
• gen_is 🔒
  Generate an is_* type-checking method.

Structs

• CoercionKind
  Describes what input types are allowed when coercing a Value to a string
• WRITE_FLOAT_OPTIONS 🔒

Enums

• PointerEquality
  Controls what kind of by-pointer equality comparison is allowed.
• Value

Traits

• TotalDisplay 🔒

Functions

• total_fmt_float 🔒
  Emulates the C++-Nix style formatting of floats, which diverges significantly from Rust’s native float formatting.
• type_error 🔒
