This PR renames the former kind enum from FromBytesWithNulErrorKind to FromBytesWithNulError, and removes the original struct. See rust-lang/libs-team#493 Possible Changes - TBD should the new en...

Also, people don't usually call FromStr::from_str directly because (1) it's not in the prelude and (2) people use .parse(). I see it as a means to an end to be more consistent with the Rust ecosystem, but we should define our own constructors on top of impl FromStr. We actu...
尝试了URLConnection.guessContentTypeFromStream(ByteArrayInputStream(bytes))和Tika().detect(bytes) 一个识别不了视频,另一个直接报一堆错 google 很久也没找到可用代码,只好自己动手 funbyteArrayOfInts(varargints:Int)= ByteArray(ints.size) { pos -> ints[pos].toByte() }valsig2mime = HashMap<Byt...
本文简要介绍rust语言中 std::ffi::CStr.from_bytes_with_nul 的用法。用法pub fn from_bytes_with_nul(bytes: &[u8]) -> Result<&CStr, FromBytesWithNulError> 从字节切片创建 C 字符串包装器。 在确保字节切片为 nul-terminated 并且不包含任何内部 nul 字节后,此函数会将提供的 bytes 转换为 CStr ...
本文简要介绍rust语言中 u32.from_be_bytes 的用法。用法pub const fn from_be_bytes(bytes: [u8; 4]) -> u32 从它的表示创建一个本地字节序整数值作为大端字节数组。例子let value = u32::from_be_bytes([0x12, 0x34, 0x56, 0x78]); assert_eq!(value, 0x12345678);...

本文简要介绍rust语言中 std::ffi::FromVecWithNulError.into_bytes 的用法。用法pub fn into_bytes(self) -> Vec<u8> 返回尝试转换为 CString 的字节。 此方法经过精心构造以避免分配。它将消耗错误,移出字节,因此不需要制作字节的副本。 例子 基本用法: use std::ffi::CString; // Some invalid bytes in...
