5.2.3

• fix: export getDependencies method. This method allows you to get all classes with schemas that extend a particular class

5.2.2

• fix: reset cached deserialisation behaviour on dynamic imports. This will allow dynamically imported classes to also be considered for Enum deserialisation

5.2.1

• feat: Custom class serializer

Custom class serialization that is useful if you want to override serialization behaviour, like doing caching

Example

import { serializer } from '@dao-xyz/borsh'
class TestStruct {

  @field({type: 'u8'})
  public number: number;

  constructor(number: number) {
    this.number = number;
  }

  cache: Uint8Array | undefined;

  @serializer()
  override(writer: BinaryWriter, serialize: (obj: this) => Uint8Array) {
    if (!this.cache) {
      this.cache = serialize(this)
    }
    writer.set(this.cache)
  }
}

5.1.8

• fix: improve error message for variant conflict (b35bf99)

5.1.7

• fix: Throw BorshError instead of Error on failing to decode bool and u8

5.1.6

• fix: add overflow checks for string decoding to coerce behaviours between protobuf/utf8 and Buffer.toString()

5.1.5

• Prevent unbound allocation for arrays on deserialization
• Reduce call stack depth when deserializing many elements

5.1.4

• Improve performance for large string encoding/decoding. See benchmark.

5.1.3

• Bug fix: Prevent u256 and u512 deserialization modifying the original serialized byte array when passed as Buffer

5.1.2

• Faster u64 serialization by handling small numbers differently

Benchmark below. Protobuf does not deserialize into bigint so these benchmarks are not easily comparable.

borsh u64 with bigint x 5,385,093 ops/sec ±0.44% (389 runs sampled)
protobujs u64 with bigint x 7,022,500 ops/sec ±0.53% (393 runs sampled)
borsh u64 with number x 6,124,037 ops/sec ±0.42% (393 runs sampled)
protobujs u64 with number x 4,639,581 ops/sec ±0.35% (394 runs sampled)
