Usage

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

// Trim leading zeros from bytes
result := data.TrimBytes([]byte{0x00, 0x00, 0x01, 0x02}, data.TrimLeft)
// []byte{0x01, 0x02}

// Trim trailing zeros from bytes
result := data.TrimBytes([]byte{0x01, 0x02, 0x00, 0x00}, data.TrimRight)
// []byte{0x01, 0x02}

// Trim leading zeros from hex string
hexResult := data.TrimHex("0x00000102", data.TrimLeft)
// "0x0102"

// Trim trailing zeros from hex string
hexResult := data.TrimHex("0x01020000", data.TrimRight)
// "0x0102"

Returns

Type: []byte for TrimBytes, string for TrimHex

The trimmed value with leading or trailing zeros removed.

Parameters

value (required)

Type: []byte for TrimBytes, string for TrimHex

The byte slice or hex string to trim.

result := data.TrimBytes([]byte{0x00, 0x00, 0x01, 0x02}, data.TrimLeft)

dir (required)

Type: data.TrimDirection (TrimLeft or TrimRight)

The direction in which to trim zeros – either leading (left) or trailing (right).

// Trim leading zeros
result := data.TrimBytes([]byte{0x00, 0x00, 0x01, 0x02}, data.TrimLeft)
// []byte{0x01, 0x02}

// Trim trailing zeros
result := data.TrimBytes([]byte{0x01, 0x02, 0x00, 0x00}, data.TrimRight)
// []byte{0x01, 0x02}

// Trim hex leading zeros
hexResult := data.TrimHex("0x00000102", data.TrimLeft)
// "0x0102"

// Trim hex trailing zeros
hexResult := data.TrimHex("0x01020000", data.TrimRight)
// "0x0102"

Convenience Functions

TrimLeftBytes / TrimRightBytes

Convenience functions for trimming bytes in a specific direction:

result := data.TrimLeftBytes([]byte{0x00, 0x00, 0x01, 0x02})
// []byte{0x01, 0x02}

result := data.TrimRightBytes([]byte{0x01, 0x02, 0x00, 0x00})
// []byte{0x01, 0x02}

TrimLeftHex / TrimRightHex

Convenience functions for trimming hex strings in a specific direction:

result := data.TrimLeftHex("0x00000102")
// "0x0102"

result := data.TrimRightHex("0x01020000")
// "0x0102"
