Macro creusot_contracts::std::prelude::rust_2018::include_bytes
1.0.0 · source · macro_rules! include_bytes { ($file:expr $(,)?) => { ... }; }
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.
§Examples
Assume there are two files in the same directory with the following contents:
File ‘spanish.in’:
adiós
File ‘main.rs’:
ⓘ
fn main() {
let bytes = include_bytes!("spanish.in");
assert_eq!(bytes, b"adi\xc3\xb3s\n");
print!("{}", String::from_utf8_lossy(bytes));
}
Compiling ‘main.rs’ and running the resulting binary will print “adiós”.
