Struct nix_compat::store_path::StorePath

pub struct StorePath {
    digest: [u8; 20],
    name: Box<str>,
}

Represents a path in the Nix store (a direct child of STORE_DIR).

It consists of a digest (20 bytes), and a name, which is a string. The name may only contain ASCII alphanumeric, or one of the following characters: -, _, ., +, ?, =. The name is usually used to describe the pname and version of a package. Derivation paths can also be represented as store paths, their names just end with the .drv prefix.

A StorePath does not encode any additional subpath “inside” the store path.

Fields

digest: [u8; 20]

name: Box<str>

Implementations

impl StorePath

pub fn digest(&self) -> &[u8; 20]

pub fn name(&self) -> &str

pub fn as_ref(&self) -> StorePathRef<'_>

impl StorePath

pub fn from_bytes(s: &[u8]) -> Result<StorePath, Error>

Construct a StorePath by passing the $digest-$name string that comes after STORE_DIR_WITH_SLASH.

pub fn from_absolute_path_full(s: &str) -> Result<(StorePath, PathBuf), Error>

Decompose a string into a StorePath and a PathBuf containing the rest of the path, or an error.

pub fn to_absolute_path(&self) -> String

Returns an absolute store path string. That is just the string representation, prefixed with the store prefix (STORE_DIR_WITH_SLASH),

Trait Implementations

impl AtermWriteable for StorePath

fn aterm_write(&self, writer: &mut impl Write) -> Result<()>

impl Clone for StorePath

fn clone(&self) -> StorePath

Returns a copy 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<'de> Deserialize<'de> for StorePath

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for StorePath

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

Formats the value using the given formatter.

impl<'a> From<&'a StorePath> for StorePathRef<'a>

fn from(_: &'a StorePath) -> Self

Converts to this type from the input type.

impl FromStr for StorePath

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

Construct a StorePath by passing the $digest-$name string that comes after STORE_DIR_WITH_SLASH.

type Err = Error

The associated error which can be returned from parsing.

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 Ord for StorePath

StorePaths are sorted by their reverse digest to match the sorting order of the nixbase32-encoded string.

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for StorePath

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for StorePath

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for StorePath

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for StorePath
