Macro include_dir_as_map 

include_dir_as_map!() { /* proc-macro */ }

The procedural macro magic that embeds files from a directory into the rust binary as a hashmap.

The input must be a string literal that represents the directory to embed. This string can contain environment variables which will be expanded at compile time.

The output is a DirMap which is an alias for HashMap<String, Vec<u8>>. This hashmap maps the relative path of each file to its contents as a vector of bytes.

By default, the files are read from the filesystem at runtime in debug mode for compilation speed. To override this behavior, enable the always-embed feature in Cargo.toml.

Panics

This function will panic if the directory does not exist or if any file in the directory cannot be read.

Examples

use include_dir_as_map::{include_dir_as_map, DirMap};

let dirmap: DirMap = include_dir_as_map!("$CARGO_MANIFEST_DIR");
let bytes = dirmap.get("Cargo.toml")?;
