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

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.

source§

impl StorePath

source

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.

source

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.

source

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),
