macro_rules! include_bytes { ($file:expr $(,)?) => { ... }; }
š¬This is a nightly-only experimental API. (
prelude_2024
)Expand description
Includes a file as a reference to a byte array.
The file is located relative to the current file (similarly to how
modules are found). The provided path is interpreted in a platform-specific
way at compile time. So, for instance, an invocation with a Windows path
containing backslashes \
would not compile correctly on Unix.
This macro will yield an expression of type &'static [u8; N]
which is
the contents of the file.
Ā§Examples
Assume there are two files in the same directory with the following contents:
File āspanish.inā:
adiĆ³s
File āmain.rsā:
ā
fn main() {
let bytes = include_bytes!("spanish.in");
assert_eq!(bytes, b"adi\xc3\xb3s\n");
print!("{}", String::from_utf8_lossy(bytes));
}
Compiling āmain.rsā and running the resulting binary will print āadiĆ³sā.
