Overview

This is a library that enables encoding/decoding of bytes to candid values

Package

MOPS

mops install candid

To setup MOPS package manage, follow the instructions from the MOPS Site

Usage

Decode

let encodedArgs : Blob = ...;
let ?args: ?[Arg.Arg] = Decoder.decode(encodedArgs) else Debug.trap("Invalid candid");

Encode

let returnArgs: [Arg.Arg] = [
    {
        type_=#bool;
        value=#bool(true)
    }
];
let encodedArgs : Blob = Encoder.encode(returnArgs);

API

Decoder

decode(candidBytes: Blob) : ?[Arg.Arg]

Decodes a series of bytes to CandiArgs. If invalid candid bytes, will return null

Encoder

encode(args: [Arg.Arg]) : Blob

Encodes an array of candid arguments to bytes

encodeToBuffer(buffer : Buffer.Buffer<Nat8>, args : [Arg.Arg]) : ()

Encodes an array of candid arguments to a byte buffer

Tag

hash(t : Tag) : Nat32

Hashes a tag name to a Nat32. If already hashed, will use hash value

hashName(name : Text) : Nat32

Hashes a tag name to a Nat32

equal(t1: Tag, t2: Tag) : Bool

Checks for equality between two tags

compare(t1: Tag, t2: Tag) : Order.Order

Compares order between two tags

Type

equal(v1: Type, v2: Type): Bool

Checks for equality between two types

hash(t : Type) : Hash.Hash

Hashes a type to a Nat32

Value

equal(v1: Value, v2: Value): Bool

Checks for equality between two values

Testing
