- Source:
Parameters:
| Name | Type | Description |
|---|---|---|
bytes |
Uint8Array
|
Returns:
- Type:
-

(inner) compareBytes(u8a1, u8a2) → {Boolean}
Compare two byte arrays.
- Source:
Parameters:
| Name | Type | Description |
|---|---|---|
u8a1 |
Uint8Array
|

(inner) csv(input, sepopt)
Parse input string as a CSV data.
- Source:
Parameters:
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
input |
String
|
csv text |
||
sep |
String
|
<optional> |
"," |
default field separator |
Returns:
Array of parsed lines - each line is an array of string fields.
(inner) hexToB64(input) → {String}
Covert a given hex-encoded string to a b64-encoded string.
- Source:
Parameters:
| Name | Type | Description |
|---|---|---|
input |
String
|
Returns:
- Type:
-
String
(inner) hexToBytes(input) → {Uint8Array}
Convert a hex-encoded string to a byte array (Uint8Array).
If given hexInput is of odd length (hexInput.length % 2 !== 0)
then the last hex-digit is treated as full byte representation,
i.e.:
hexToBytes("fa6") <=> hexToBytes("fa06") <=> Uint8Array [ 250, 6 ]
All unrecognized hex-digit groups (e.g. "zz") are treated
by parseInt() as NaN and then effectively converted
to Uint8Array [ 0 ].
Input parameter (hexInput) can be prefixed with 0x.
All whitespaces, tabs and carriage returns are stripped out from the input.

Parameters:
| Name | Type | Description |
|---|---|---|
input |
String
|
Returns:
- Type:
-
Uint8Array
