Struct mod_mgmt::NamespaceDir

pub struct NamespaceDir(/* private fields */);

A wrapper around a Directory reference that offers special convenience functions for getting and inserting crate object files into a directory.

Auto-derefs into a DirRef.

Implementations

impl NamespaceDir

pub fn new(dir: DirRef) -> NamespaceDir

Creates a new NamespaceDir that wraps the given DirRef.

pub fn get_file_starting_with(&self, prefix: &str) -> Option<FileRef>

Finds the single file in this directory whose name starts with the given prefix.

Return

If a single file matches, then that file is returned. Otherwise, if no files or multiple files match, then None is returned.

pub fn get_files_starting_with(&self, prefix: &str) -> Vec<FileRef>

Returns the list of files in this Directory whose name starts with the given prefix.

pub fn get_file_and_dir_names_starting_with(&self, prefix: &str) -> Vec<String>

Returns the list of file and directory names in this Directory whose name start with the given prefix.

pub fn get_crate_object_file( &self, crate_module_file_name: &str ) -> Option<FileRef>

Gets the given object file based on its crate name prefix.

Arguments

• crate_object_file_name: the name of the object file to be returned, with or without a preceding CrateType prefix.

Examples

• The name “k#keyboard-36be916209949cef.o” will look for and return the file “keyboard-36be916209949cef.o”.
• The name “keyboard-36be916209949cef.o” will look for and return the file “keyboard-36be916209949cef.o”.
• The name “a#ps.o” will look for and return the file “ps.o”.

pub fn write_crate_object_file( &self, crate_object_file_name: &str, content: &[u8] ) -> Result<FileRef, &'static str>

Insert the given crate object file based on its crate type prefix.

Arguments

• crate_object_file_name: the name of the object file to be inserted, with a preceding CrateType prefix.
• content: the bytes that will be written into the file.

Examples

• The file “k#keyboard-36be916209949cef.o” will be written to “./keyboard-36be916209949cef.o”.
• The file “a#ps.o” will be placed into “./ps.o”.
