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.

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

Enums

PointerEquality

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

Value

Statics

WRITE_FLOAT_OPTIONS 🔒

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 🔒
