Struct nix_query_tree_viewer::nix_query_tree::NixQueryDrv

pub struct NixQueryDrv(_);

This corresponds to a nix store path.

use nix_query_tree_viewer::nix_query_tree::NixQueryDrv;

let nix_query_drv =
    NixQueryDrv::from("/nix/store/qy93dp4a3rqyn2mz63fbxjg228hffwyw-hello-2.10");

Methods

impl NixQueryDrv

pub fn cmp_hash(&self, other: &Self) -> Ordering

pub fn cmp_drv_name(&self, other: &Self) -> Ordering

pub fn hash_and_drv_name(&self) -> String

Pull out the hash and derivation name from a NixQueryDrv

use nix_query_tree_viewer::nix_query_tree::NixQueryDrv;

let nix_query_drv =
    NixQueryDrv::from("/nix/store/az4kl5slhbkmmy4vj98z3hzxxkan7zza-gnugrep-3.3");
assert_eq!(
    nix_query_drv.hash_and_drv_name(),
    String::from("az4kl5slhbkmmy4vj98z3hzxxkan7zza-gnugrep-3.3")
);

pub fn short_hash_and_drv_name(&self) -> String

Pull out a truncated hash and derivation name from a NixQueryDrv

use nix_query_tree_viewer::nix_query_tree::NixQueryDrv;

let nix_query_drv =
    NixQueryDrv::from("/nix/store/az4kl5slhbkmmy4vj98z3hzxxkan7zza-gnugrep-3.3");
assert_eq!(
    nix_query_drv.short_hash_and_drv_name(),
    String::from("az4kl5s..gnugrep-3.3")
);

pub fn drv_name(&self) -> String

Pull out a derivation name from a NixQueryDrv.

use nix_query_tree_viewer::nix_query_tree::NixQueryDrv;

let nix_query_drv =
    NixQueryDrv::from("/nix/store/az4kl5slhbkmmy4vj98z3hzxxkan7zza-gnugrep-3.3");
assert_eq!(nix_query_drv.drv_name(), String::from("gnugrep-3.3"));

• Panics

This panics if the derivation name doesn't have a - in it. All nix derivations have a - in them after the hash.
