Struct cor_args::FileHandler

pub struct FileHandler { /* private fields */ }

A handler for retrieving values from a file.

This struct is responsible for handling requests by checking for values within a specified file. (The actual file reading logic is not yet implemented in the provided code.)

Implementations

impl FileHandler

pub fn new<P>(file_path: P) -> Self

where P: Into<PathBuf>,

Creates a new FileHandler with the specified file path and an optional next handler.

Arguments

• file_path - The path to the file from which values are to be retrieved.
• next - An optional next handler to which requests can be delegated if this handler can’t fulfill them.

pub fn next(self, handler: Box<dyn Handler>) -> Self

Trait Implementations

impl Handler for FileHandler

fn handle_request(&self, key: &str) -> Option<String>

Retrieves content from the specified file.

This implementation attempts to read content from the file specified by file_path. If reading fails, and if a next handler is provided, it delegates the request to the next handler. If there’s no next handler or if the file reading fails, it returns None.

Arguments

• key - The key for which the value needs to be retrieved. (Note: The key is currently unused in the reading logic.)

impl Into<Box<dyn Handler>> for FileHandler

fn into(self) -> Box<dyn Handler>

Converts this type into the (usually inferred) input type.
