func NewFIFOMap[K comparable, V any](size, shards int, hashFn HashFn[K]) *FIFOMap[K, V]

NewFIFOMap returns a FIFO map that internally uses the sharded map. It keeps count of all the items inserted, and when we exceed the size, values will be evicted using the FIFO (first in, first out) policy.

type RawCommitmentBuilder added in v0.8.22 

type RawCommitmentBuilder struct {
	// contains filtered or unexported fields
}

func NewRawCommitmentBuilder added in v0.8.22 

func NewRawCommitmentBuilder(name string) *RawCommitmentBuilder

func (*RawCommitmentBuilder) ConstantString added in v0.8.22 

func (b *RawCommitmentBuilder) ConstantString(s string) *RawCommitmentBuilder

Append a constant string to the running hash.

WARNING: The string `s` must be a constant. This function does not encode the length of `s` in the hash, which can lead to domain collisions when different strings with different lengths are used depending on the input object.

func (*RawCommitmentBuilder) Field added in v0.8.22 

func (b *RawCommitmentBuilder) Field(f string, c Commitment) *RawCommitmentBuilder

Include a named field of another committable type.

func (*RawCommitmentBuilder) Finalize added in v0.8.22 

func (b *RawCommitmentBuilder) Finalize() Commitment

func (*RawCommitmentBuilder) FixedSizeBytes added in v0.8.22 

func (b *RawCommitmentBuilder) FixedSizeBytes(bytes Bytes) *RawCommitmentBuilder

Append a fixed size byte array to the running hash.

WARNING: Go's type system cannot express the requirement that `bytes` is a fixed size array of any size. The best we can do is take a dynamically sized slice. However, this function uses a fixed-size encoding; namely, it does not encode the length of `bytes` in the hash, which can lead to domain collisions when this function is called with a slice which can have different lengths depending on the input object.

The caller must ensure that this function is only used with slices whose length is statically determined by the type being committed to.

func (*RawCommitmentBuilder) FixedSizeField added in v0.8.22 

func (b *RawCommitmentBuilder) FixedSizeField(f string, bytes Bytes) *RawCommitmentBuilder

Include a named field of fixed length in the hash.

func (*RawCommitmentBuilder) OptionalField added in v0.8.22 

func (b *RawCommitmentBuilder) OptionalField(f string, c *Commitment) *RawCommitmentBuilder

func (*RawCommitmentBuilder) Uint256 added in v0.8.22

Include a value of type `uint256` in the hash.

func (*RawCommitmentBuilder) Uint256Field added in v0.8.22 

func (b *RawCommitmentBuilder) Uint256Field(f string, n *U256) *RawCommitmentBuilder

Include a named field of type `uint256` in the hash.

func (*RawCommitmentBuilder) Uint64 added in v0.8.22 

func (b *RawCommitmentBuilder) Uint64(n uint64) *RawCommitmentBuilder

Include a value of type `uint64` in the hash.

func (*RawCommitmentBuilder) Uint64Field added in v0.8.22 

func (b *RawCommitmentBuilder) Uint64Field(f string, n uint64) *RawCommitmentBuilder

Include a named field of type `uint64` in the hash.

func (b *RawCommitmentBuilder) VarSizeField(f string, bytes Bytes) *RawCommitmentBuilder

Include a named field of dynamic length in the hash.

type ShardedMap 

type ShardedMap[K comparable, V any] struct {
	// contains filtered or unexported fields

func NewShardedMap 

func NewShardedMap[K comparable, V any](size, numShards int, hashFn HashFn[K]) *ShardedMap[K, V]

NewShardedMap returns a new sharded map with `numShards` shards. Each of the shards are pre-allocated with a length of `size` / `numShards`. `size` is not the max size by any means, but just an estimation. hashFn is used to hash the key.

func (*ShardedMap[K, V]) Del 

func (m *ShardedMap[K, V]) Del(key K)

Del deletes the value from the map.

func (*ShardedMap[K, V]) Get 

func (m *ShardedMap[K, V]) Get(key K) (v V, ok bool)

Get returns the value and true if the value is present, otherwise it returns the default value and false.

func (*ShardedMap[K, V]) Has 

func (m *ShardedMap[K, V]) Has(key K) bool

Has returns true if the key is present.

func (*ShardedMap[K, V]) Len 

func (m *ShardedMap[K, V]) Len() int

Len returns the count of all the items in the sharded map. It will RLock every one of the shards so use it scarcely.

func (*ShardedMap[K, V]) Put 

func (m *ShardedMap[K, V]) Put(key K, val V)

Put puts the key value pair in the map.

type U256 

type U256 struct {
	big.Int
}

A BigInt type which serializes to JSON a a hex string.
