Struct StorePath 

pub struct StorePath {
    pub digest: [u8; 20],
    pub name: String,
}

A validated Nix store path.

Fields

digest: [u8; 20]

The 20-byte hash digest.

name: String

The human-readable name portion.

Implementations

impl StorePath

pub fn from_absolute_path(path: &str) -> Result<Self, StorePathError>

Parse a store path from a string like /nix/store/<hash>-<name>.

pub fn from_basename(basename: &str) -> Result<Self, StorePathError>

Parse from just the <hash>-<name> portion.

pub fn to_absolute_path(&self) -> String

Render the full absolute path.

pub fn to_basename(&self) -> String

Render just the <hash>-<name> basename.

pub fn hash(&self) -> String

Return the Nix base-32 hash portion of this store path.

This is the 32-character string used to look up .narinfo files in binary caches (e.g., sn5lbjwwmkbzj7cx0hfnlwf4sh16cll6).

pub fn name(&self) -> &str

Return the human-readable name portion of this store path (e.g., hello-2.12.1).

Trait Implementations

impl Clone for StorePath

fn clone(&self) -> StorePath

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StorePath

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for StorePath

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for StorePath

impl FromStr for StorePath

type Err = StorePathError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for StorePath

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for StorePath

fn eq(&self, other: &StorePath) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
