Crate utf8_command
source ·Expand description
Provides the Utf8Output
type, a UTF-8-decoded variant of std::process::Output
(as
produced by std::process::Command::output
).
Construct Utf8Output
from Output
via the TryInto
or TryFrom
traits:
let output: Utf8Output = Command::new("echo")
.arg("puppy")
.output()
.unwrap()
.try_into()
.unwrap();
assert_eq!(
output,
Utf8Output {
status: ExitStatus::default(),
stdout: String::from("puppy\n"),
stderr: String::from(""),
},
);
Error messages will include information about the stream that failed to decode, as well as the output (with invalid UTF-8 bytes replaced with U+FFFD REPLACEMENT CHARACTER):
let invalid = Output {
status: ExitStatus::default(),
stdout: Vec::from(b"puppy doggy \xc3\x28"), // Invalid 2-byte sequence.
stderr: Vec::from(b""),
};
let err: Result<Utf8Output, Error> = invalid.try_into();
assert_eq!(
err.unwrap_err().to_string(),
"Stdout contained invalid utf-8 sequence of 1 bytes from index 12: \"puppy doggy �(\""
);
