Struct FileLoader

pub struct FileLoader { /* private fields */ }

The FileLoader struct is responsible for loading files from a specified directory, filtering them based on their extensions, and creating a stream of these files for further processing.

Example

Create a pipeline that loads the current directory and indexes all files with the “.rs”

indexing::Pipeline::from_loader(FileLoader::new(".").with_extensions(&["rs"]));

Implementations

impl FileLoader

pub fn new(root: impl AsRef<Path>) -> Self

Creates a new FileLoader with the specified path.

Arguments

• root: The root directory to load files from.

Returns

A new instance of FileLoader.

pub fn with_extensions(self, extensions: &[impl AsRef<str>]) -> Self

Adds extensions to the loader.

Arguments

• extensions: A list of extensions to add without the leading dot.

Returns

The FileLoader instance with the added extensions.

pub fn list_nodes(&self) -> Vec<Node>

Lists the nodes (files) that match the specified extensions.

Returns

A vector of Node representing the matching files.

Panics

This method will panic if it fails to read a file’s content.

pub fn iter(&self) -> impl Iterator<Item = Result<Node>> + use<>

Iterates over the files in the directory
