prototype

Combines two Results such that if they're both successful (Ok) their values are concatenated. Otherwise returns the failure.

Performs a deep-comparison of two Result values for equality. See adt/union/derivations/equality for details.

Tests if an arbitrary value is a Result instance.

Constructs a Result holding an Ok value.

Transforms a Result into a Maybe. Error values are lost in the process.

Transforms a Result into a Validation.

The value contained in an Error instance of the Result structure.

A textual representation for Result instances.

A textual representation for Result instances.

Extracts the value of a Result structure, if it exists (i.e.: is an Ok), otherwise returns the provided default value.

Returns the value inside of the Result structure, regardless of its state.

Extracts the value from a Result structure.

Allows a function to provide functionality to variants in an union.

Applies a function to each case of a Result.

Chooses and executes a function for each variant in the Result structure.

Allows recovering from Error values with a handler function.

Inverts the context of a Result value such that Errors are transformed into Oks, and Oks are transformed into Errors. Does not touch the value inside of the Result.

Parses a JavaScript object previously serialised as aResult.toJSON() into a proper Result structure.

Converts a Result value to a JavaScript object that may be stored as a JSON value.

The constructor for this variant.

The variants in the Result structure.

Applies the function contained in one Result to the value in another Result. Application only occurs if both Results are Ok, otherwise keeps the first Error.

Transforms each side of a Result with a function, without changing the context of the computation. That is, Errors will still be Errors, Oks will still be Oks.

Transforms the value and context of a Result computation with an unary function. As with .map(), the transformation is only applied if the value is an Ok, but the transformation is expected a new Result value, which then becomes the result of the method.

If the Result is a Ok, passes its value to the predicate. If the predicate returns true, then the Result is returned unchanged. In every other case, an Error gets returned.

Transforms the value inside of a Result structure with an unary function without changing the context of the computation. That is, Error values continue to be Error values, and Ok values continue to be Ok values.

Transforms the value inside an Error without changing the context of the computation.

Constructs a Result whose value represents a failure.

Constructs a Result whose value represents a success.
