Struct std.digest.crc.CRC32

Template API CRC32 implementation. See std.digest.digest for differences between template and OOP API.

Methods

Name Description
finish Returns the finished CRC32 hash. This also calls start to reset the internal state.
peek Works like finish but does not reset the internal state, so it's possible to continue putting data into this CRC32 after a call to peek.
put Use this to feed the digest with data. Also implements the std.range.primitives.isOutputRange interface for ubyte and const(ubyte)[].
start Used to initialize the CRC32 digest.

Example

//Simple example, hashing a string using crc32Of helper function
ubyte[4] hash = crc32Of("abc");
//Let's get a hash string
assert(crcHexString(hash) == "352441C2");

Example

//Using the basic API
CRC32 hash;
ubyte[1024] data;
//Initialize data here...
hash.put(data);
ubyte[4] result = hash.finish();

Example

//Let's use the template features:
//Note: When passing a CRC32 to a function, it must be passed by reference!
void doSomething(T)(ref T hash) if(isDigest!T)
{
  hash.put(cast(ubyte)0);
}
CRC32 crc;
crc.start();
doSomething(crc);
assert(crcHexString(crc.finish()) == "D202EF8D");
