Function kernel::fs::mapping::on_all_matching_mappings

pub fn on_all_matching_mappings(
    inp_path: &Path,
    handler: impl FnMut(&Path, Arc<dyn FileSystem>)
) -> Result<(), FileSystemError>

Traverses the filesystem mapping tree and applies a handler function to all matching mappings.

This function iterates through the filesystem mapping tree, starting from the root, and applies a handler function to all nodes whose paths match the provided input path. The matching is performed by comparing the components of the input path with the components of the mapping paths.

Parameters

• inp_path: A reference to the input path for which matching mappings need to be found. The input path must be absolute and not contain any “..” or “.” components.

• handler: A closure or function that takes a reference to a path and an Arc smart pointer to a trait object implementing the FileSystem trait. This closure or function will be applied to each matching mapping.

Returns

• Ok(()): If the traversal and application of the handler function are successful.

• Err(FileSystemError): If an error occurs during the traversal or application of the handler function. The specific error can be one of the following:

  • FileSystemError::MustBeAbsolute: If the provided input path is not absolute.
  • FileSystemError::InvalidPath: If the provided input path contains “..” or “.” components.
