CalculateChecksum calculates checksum for data using ct checksum type.

Check logs fatal if err != nil.

Check2 acts as convenience wrapper around Check, using the 2nd argument as error.

CompareKeys checks the key without timestamp and checks the timestamp if keyNoTs is same.

Copy copies a byte slice and returns the copied slice.

CreateSyncedFile creates a new file (using O_EXCL), errors if it already existed.

FixedDuration returns a string representation of the given duration with the hours, minutes, and seconds.

GenerateIV generates IV.

hash implements a hashing algorithm similar to the Murmur hash.

IBytesToString converts size in bytes to human readable format.

KeyWithTs generates a new key by appending ts to key.

NewFilter returns a new Bloom filter that encodes a set of []byte keys with the given number of bits per key, approximately.

NewPageBuffer returns a new PageBuffer with first page having size pageSize.

VerifyChecksum validates the checksum for the data against the given expected checksum.

Wrap wraps errors from external lib.

Wrapf is Wrap with extra info.

XORBlock encrypts the given data with AES and XOR's with IV.

ZSTDCompress compresses a block using ZSTD algorithm.

ZSTDCompressBound returns the worst case size needed for a destination buffer.

ZSTDDecompress decompresses a block using ZSTD algorithm.

ReadOnly opens the underlying file on a read-only basis.

Sync indicates that O_DSYNC should be set on the underlying file, ensuring that data writes do not return until the data is flushed to disk.

CastagnoliCrcTable is a CRC32 polynomial table.

ErrChecksumMismatch is returned at checksum mismatch.

ErrEOF indicates an end of file when trying to read from a memory mapped file and encountering the end of slice.

PageBuffer consists of many pages.

PageBufferReader is a reader for PageBuffer.

Slice holds a reusable buf, will reallocate if you request a larger size than ever before.

Throttle allows a limited number of workers to run at a time.
