Abstract Readonly fixedReadonly nameName of this codec used to export .mol file.
Protected Abstract _unpackCreate a new codec which shares the same underlying molecule type but with different JavaScript type.
This is useful to create a different view wrapper.
import { mol } from "@ckb-cobuild/molecule";
const ByteOpt = mol.option("ByteOpt", mol.byte);
const BooleanOpt = ByteOpt.around({
safeParse: (input: boolean | null) => mol.parseSuccess(input),
willPack: (input: boolean | null) =>
input !== null ? (input ? 1 : 0) : null,
didUnpack: (value: number | null) => (value !== null ? value !== 0 : null),
});
Chain a parse method before.
import { mol } from "@ckb-cobuild/molecule";
const ByteCoerce = mol.byte.beforeParse((input: any) => Number(input));
Chain a safeParse method before.
import { mol } from "@ckb-cobuild/molecule";
const ByteCoerce = mol.byte.beforeSafeParse((input: any) => {
const result = parseInt(input);
if (!Number.isNaN(result)) {
return mol.parseSuccess(result);
}
return mol.parseError("Not a number");
});
Direct dependencies of this codec.
Abstract getAbstract packPack the value and append the buffer to the provided writer.
Take the advantage of writer and append the buffer as blocks. The writer can concatenate all blocks into one buffer for the final result.
Parse a compatible input.
Abstract safeParse a compatible input. Return a result instead of throwing.
Generated using TypeDoc
The fixed size codec does not require length header when used inside other structures.
