either clj

(either on-left on-right val0)

Evaluates val0' a monadic sub-routine of type Either, and callson-left' or `on-right' depending on the resulting Either value

from-left clj

(from-left def e)

Unwraps Either value when it is left, otherwise return def

from-right clj

(from-right def e)

Unwraps Either value when it is right, otherwise return def

left clj

(left val)

Wraps val on an Either's left value, normally corresponds to an error value

left-map clj

(left-map f val)

Calls f' on the wrapped Either value when wrapper is aleft'

left? clj

(left? val)

Checks if `val' corresponds to an Either's left value. If it receives a monadic sub-routine it will evaluate it, careful if your monadic sub-routine performs side-effects)

or-else clj

(or-else es)

Returns first Right value from seq

or-else* clj

(or-else* e0 & rem0)

Returns first argument that has a Right value

right clj

(right val)

Wraps val on an Either's right value

right? clj

(right? val)

Checks if `val' corresponds to an Either's right value. If it receives a monadic sub-routine it will evaluate it, careful if your monadic sub-routine performs side-effects)

run-either clj

(run-either action)

Evaluates a monadic sub-routine of type Either

try-either clj macro

(try-either io-action)

(try-either io-action on-failure)

Performs a call that might fail and wraps its result on an Either.

When the call throws an exception, the exception is wrapped on a left' value; otherwise aright' value is returned.

When an on-failure' function is given, it will be called with the received exception, and the returned value is returned wrapped on aleft' value
