Struct ImportedLockedFlake 

pub struct ImportedLockedFlake { /* private fields */ }

A locked flake graph imported from an owned export payload.

This is intentionally narrower than LockedFlake. It contains enough graph state to evaluate outputs through Nix’s callFlake, but it is not a general-purpose replacement for a flake freshly returned by LockedFlake::lock.

Implementations

impl ImportedLockedFlake

pub fn import_json( context: &Arc<Context>, fetch_settings: &FetchersSettings, json: &str, ) -> Result<Self>

Import a locked flake graph from an owned JSON graph.

The root flake and inputs are taken from json; this does not resolve a flake reference, update inputs, or write a lock file.

Errors

Returns an error if the C API call fails or returns a null pointer.

pub fn output_attrs<'s>( &self, flake_settings: &FlakeSettings, eval_state: &'s EvalState, ) -> Result<Value<'s>>

Get the output attributes of this imported graph as a Nix value.

The returned Value is tied to the lifetime of eval_state.

Errors

Returns an error if the C API call fails.
