Struct PgsReader 

pub struct PgsReader {}

A struct for handling the opening of files to create PgsFile instances.

Currently, this struct does not maintain any internal state but provides a method to open a file and return a PgsFile instance.

Implementations

impl PgsReader

pub fn open(sup_file_path: &str) -> Result<PgsFile>

Opens a file and returns a PgsFile instance.

This method checks if the specified file exists and then attempts to open it. If successful, it creates a new PgsFile instance using the opened file.

Arguments

• sup_file_path - A string slice representing the path to the file to be opened.

Returns

Returns a Result containing either a PgsFile instance on success or an Error if the file does not exist, cannot be opened, or if creating the PgsFile instance fails.

Errors

• Error::File - If the file does not exist or if the file cannot be opened.
• Any other Error arising from PgsFile::new or file operations.
