Error Set ReadError [src]

Errors

AccessDenied

In WASI, this error occurs when the file descriptor does not hold the required rights to read from it.

BrokenPipe

Canceled

reading a timerfd with CANCEL_ON_SET will lead to this error when the clock goes through a discontinuous change

ConnectionResetByPeer

ConnectionTimedOut

InputOutput

IsDir

LockViolation

Unable to read file due to lock.

NotOpenForReading

OperationAborted

ProcessNotFound

This error occurs in Linux if the process to be read from no longer exists.

SocketNotConnected

SystemResources

Unexpected UnexpectedError

The Operating System returned an undocumented error code.

This error is in theory not possible, but it would be better to handle this error than to invoke undefined behavior.

When this error code is observed, it usually means the Zig Standard Library needs a small patch to add the error code to the error set for the respective function.

WouldBlock

This error occurs when no global event loop is configured, and reading from the file descriptor would block.
