FileReadWithResult

eff FileReadWithResultSource

An effect used to read from the file system.

Operations

def accessTime(f: String): Result[IoError, Int64] \ FileReadWithResult Source

Returns the last access time of the given file f in milliseconds since the epoch.

def creationTime(f: String): Result[IoError, Int64] \ FileReadWithResult Source

Returns the creation time of the given file f in milliseconds since the epoch.

def exists(f: String): Result[IoError, Bool] \ FileReadWithResult Source

Returns true if the given file f exists.

def isDirectory(f: String): Result[IoError, Bool] \ FileReadWithResult Source

Returns true is the given file f is a directory.

def isExecutable(f: String): Result[IoError, Bool] \ FileReadWithResult Source

Returns true if the given file f is executable.

def isReadable(f: String): Result[IoError, Bool] \ FileReadWithResult Source

Returns true if the given file f is readable.

def isRegularFile(f: String): Result[IoError, Bool] \ FileReadWithResult Source

Returns true if the given file f is a regular file.

def isSymbolicLink(f: String): Result[IoError, Bool] \ FileReadWithResult Source

Returns true if the given file f is a symbolic link.

def isWritable(f: String): Result[IoError, Bool] \ FileReadWithResult Source

Returns true if the given file f is writable.

def list(f: String): Result[IoError, List[String]] \ FileReadWithResult Source

Returns a list with the names of all files and directories in the given directory d.

def modificationTime(f: String): Result[IoError, Int64] \ FileReadWithResult Source

Returns the last-modified timestamp of the given file f in milliseconds since the epoch.

def read(f: String): Result[IoError, String] \ FileReadWithResult Source

Returns a string of all lines in the given file f.

def readBytes(f: String): Result[IoError, Vector[Int8]] \ FileReadWithResult Source

Returns a vector of all the bytes in the given file f.

def readLines(f: String): Result[IoError, List[String]] \ FileReadWithResult Source

Returns a list of all lines in the given file f.

def size(f: String): Result[IoError, Int64] \ FileReadWithResult Source

Returns the size of the given file f in bytes.

def handle(f: a -> b \ ef): a -> b \ (ef - FileReadWithResult) + IO Source

Handles the FileReadWithResult effect of the given function f.

In other words, re-interprets the FileReadWithResult effect using the IO effect.

def runWithIO(f: Unit -> a \ ef): a \ (ef - FileReadWithResult) + IO Source

Runs the FileReadWithResult effect of the given function f.

In other words, re-interprets the FileReadWithResult effect using the IO effect.
