Macro std::include_str
1.0.0 · source · macro_rules! include_str { ($file:expr $(,)?) => { ... }; }
Expand description
Includes a UTF-8 encoded file as a string.
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 str
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 my_str = include_str!("spanish.in");
assert_eq!(my_str, "adiós\n");
print!("{my_str}");
}
RunCompiling ‘main.rs’ and running the resulting binary will print “adiós”.
