Struct Derivation 

pub struct Derivation { /* private fields */ }

A Nix derivation

Requires Nix 2.33 or later.

Implementations

impl Derivation

pub fn to_json_string(&self) -> Result<String>

Convert the derivation to JSON (which is encoded to a string).

Requires Nix 2.33 or later.

The JSON format follows the Nix derivation JSON schema. Note that this format is experimental as of writing.

pub unsafe fn new_raw_clone(inner: NonNull<derivation>) -> Self

This is a low level function that you shouldn’t have to call unless you are developing the Nix bindings.

Construct a new Derivation by first cloning the C derivation.

Safety

This does not take ownership of the C derivation, so it should be a borrowed pointer, or you should free it.

pub unsafe fn as_ptr(&self) -> *mut derivation

This is a low level function that you shouldn’t have to call unless you are developing the Nix bindings.

Get a pointer to the underlying Nix C API derivation.

Safety

This function is unsafe because it returns a raw pointer. The caller must ensure that the pointer is not used beyond the lifetime of this Derivation.

Trait Implementations
