Times returns the product of t and u as elements of GF(2^16).

RootDir returns a string representing a root directory. On Unix-like systems this is just /, but on Windows it may be C:\ or some other drive letter.

LoadFileData loads existing file data into memory.

At returns the element at row index i and column index j.

LoadFileData loads existing file data into memory.

LoadParityData searches for parity volumes and loads them into memory.

NewMatrixFromSlice returns a rows x columns matrix with elements taken from the given array in row-major order.

ShardCounts returns a ShardCounts object for the current shard set.

Inverse returns the multiplicative inverse of t, if t != 0. It panics if t == 0.

RemoveFile removes the file at the given path, which may be absolute or relative (to the working directory). The removed data is returned, or os.ErrNo

NewMatrixFromFunction returns a rows x columns matrix with elements filled in from the given function, which is passed the row index and the column in

Paths returns a list of absolute paths of files in fs in no particular order.

Pow returns the t^p as an element of GF(2^16). T(0).Pow(0) returns 1.

DefaultNumGoroutines returns a default value for the numGoroutines parameter to pass into NewCoderCauchy and NewCoderPAR2Vandermonde. This is not nece

Div returns the product of t and u^{-1} as elements of GF(2^16), if u != 0. It panics if u == 0.

GenerateParity takes a list of data shards, which must have length matching the dataShards value passed into NewCoder, and which must have equal-sized

MakeMemFS makes a MemFS from the given working directory and file data.

VerifyAllData checks and returns whether all data and parity files contain correct data. Note that this is worth calling only when there are no unusab

FileCounts returns a FileCounts object for the current file set.

NumGoroutinesDefault returns the default value used for CreateOptions.NumGoRoutines the latter is <= 0.

crcz32 is the function such that crc32.ChecksumIEEE(a) = ffffffff ^ crcz(ffffffff.. ^ a).

crcz32ReverseBytesShiftLeft returns crcz32(reverseBytes(a) << n), where reverseBytes() maps math.bits.Reverse8 over all bytes of a, given crcz32(a) an

NewCoderPAR2Vandermonde returns a Coder that works with the given number of data and parity shards, using a Vandermonde matrix as specified in the PAR

ReconstructData takes a list of data shards and parity shards, some of which may be nil, and tries to reconstruct the missing data shards. If successf

Repair tries to repair any missing or corrupt data, using the parity volumes. Returns a list of paths to files that were successfully repaired (relati

crc32ReverseBytesShiftLeft returns crc32(reverseBytes(a) << n), given crc32(a), crc32(len(a) copies of 0), and crc32(len(reverseBytes(a) << n) copies

row returns a slice into m.elements, so caller must not mutate except for local temporary arrays.

NewIdentityMatrix returns an n x n identity matrix.

ilog2(n) returns floor(log2(n)), assuming n > 0.

The mutating functions below must not be called except on local temporary arrays.

update returns the crc (crc32.ChecksumIEEE) of a[1:n+1], given the crc of a[0:n], oldLeader = a[0], and newTrailer = a[n], where n is the window size,

ComputeParityData computes the parity data for the files.

ComputeParityData computes the parity data for the files.

FileCount returns the total number of files.

MoveFile moves the file at oldPath to newPath. oldPath and newPath may be either absolute or relative (to the working directory). If the file doesn't

MulAndAddByteSliceLE treats in and out as arrays of Ts stored in little-endian format, and adds c.Times(in<T>[i]) to out<T>[i], for each i.

MulByteSliceLE treats in and out as arrays of Ts stored in little-endian format, and sets each out<T>[i] to c.Times(in<T>[i]).
