Struct Feature

pub struct Feature { /* private fields */ }

A Ruby source (“feature”) that has been loaded into an interpreter.

Features can either be loaded from disk or from memory.

Features are identified by the (potentially relative) path used when loading the file for the first time. Features loaded from disk are deduplicated by their real position on the underlying file system (i.e. their device and inode).

Implementations

impl Feature

pub fn with_handle_and_path(handle: Handle, path: PathBuf) -> Self

Available on crate feature disk only.

Create a new feature from a file handle and path.

pub fn with_in_memory_path(path: PathBuf) -> Self

Create a new feature from a virtual in-memory path.

Examples

use std::path::Path;
use mezzaluna_loaded_features::Feature;

let feature = Feature::with_in_memory_path("/src/_lib/test.rb".into());
assert_eq!(feature.path(), Path::new("/src/_lib/test.rb"));

pub fn path(&self) -> &Path

Get the path associated with this feature.

The path returned by this method is not guaranteed to be the same as the path returned by LoadedFeatures::features since features may be deduplicated by their physical location in the underlying loaders.

Examples

use std::path::Path;
use mezzaluna_loaded_features::Feature;

let feature = Feature::with_in_memory_path("/src/_lib/test.rb".into());
assert_eq!(feature.path(), Path::new("/src/_lib/test.rb"));

Trait Implementations

impl Debug for Feature

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

Formats the value using the given formatter.

impl Hash for Feature

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 Feature

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