Struct NixSearchPath

pub struct NixSearchPath {
    entries: Vec<NixSearchPathEntry>,
}

Struct implementing the format and path resolution rules of the NIX_PATH environment variable.

This struct can be constructed by parsing a string using the FromStr impl, or via str::parse. Nix <...> paths can then be resolved using NixSearchPath::resolve.

Fields

entries: Vec<NixSearchPathEntry>

Implementations

impl NixSearchPath

pub fn resolve<P, IO>( &self, io: IO, path: P, ) -> Result<Result<PathBuf, CatchableErrorKind>, ErrorKind>

where P: AsRef<Path>, IO: AsRef<dyn EvalIO>,

Attempt to resolve the given path within this NixSearchPath using the path resolution rules for <...>-style paths

Trait Implementations

impl Clone for NixSearchPath

fn clone(&self) -> NixSearchPath

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NixSearchPath

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

Formats the value using the given formatter.

impl Default for NixSearchPath

fn default() -> NixSearchPath

Returns the “default value” for a type.

impl FromStr for NixSearchPath

type Err = Infallible

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 PartialEq for NixSearchPath

fn eq(&self, other: &NixSearchPath) -> 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.
