Concatenates multiple byte slices or hex strings into a single value.

Import

import "github.com/ChefBingbong/viem-go/utils/data"

Usage

import "github.com/ChefBingbong/viem-go/utils/data"

// Concatenate byte slices
result := data.Concat([]byte{0x01}, []byte{0x02}, []byte{0x03})
// []byte{0x01, 0x02, 0x03}

// Concatenate hex strings
hexResult := data.ConcatHex("0x01", "0x02", "0x03")
// "0x010203"

Returns

• Type: []byte for Concat/ConcatBytes, string for ConcatHex

The concatenated value. For byte slices, returns []byte. For hex strings, returns a hex string with 0x prefix.

Parameters

values (required)

• Type: ...[]byte for Concat/ConcatBytes, ...string for ConcatHex

One or more byte slices or hex strings to concatenate.

// Concatenate multiple byte slices
result := data.ConcatBytes(
  []byte{0x01, 0x02},
  []byte{0x03, 0x04},
  []byte{0x05},
)
// []byte{0x01, 0x02, 0x03, 0x04, 0x05}

// Concatenate multiple hex strings
hexResult := data.ConcatHex(
  "0x0102",
  "0x0304",
  "0x05",
)
// "0x0102030405"

Functions

Concat

Generic function that automatically detects the type based on the first element. For byte slices, use ConcatBytes explicitly.

ConcatBytes

Concatenates multiple byte slices into one.

ConcatHex

Concatenates multiple hex strings into one. All inputs should have 0x prefix.
