getConstantEncoder

getConstantEncoder<TConstant>(constant): FixedSizeEncoder<void, TConstant["length"]>

Returns an encoder that always writes a predefined constant byte sequence.

This encoder ensures that encoding always produces the specified byte array, ignoring any input values.

For more details, see getConstantCodec.

Type Parameters

Parameters

Returns

FixedSizeEncoder<void, TConstant["length"]>

A FixedSizeEncoder<void, N> where N is the length of the constant.

Example

Encoding a constant magic number.

const encoder = getConstantEncoder(new Uint8Array([1, 2, 3, 4]));
 
const bytes = encoder.encode();
// 0x01020304
//   └──────┘ The predefined 4-byte constant.
