BcsWriter class
Class used to write BCS data into a buffer. Initializer requires some size of a buffer to init; default value for this buffer is 1KB.
Most methods are chainable, so it is possible to write them in one go.
final serialized = BcsWriter()
.write8(10)
.write32(1000000)
.write64(BigInt.from(10000001000000))
.hex();

-
write16(
int value) → BcsWriter - Write a U16 value into a buffer and shift cursor position by 2.
-
write256(
BigInt value) → BcsWriter - Write a U256 value into a buffer and shift cursor position by 32.

int value) → BcsWriter - Write a ULEB value into a buffer and shift cursor position by number of bytes written.
-
writeVec(
dynamic vector, dynamic cb(BcsWriter writer, dynamic el, int i, int len)) → BcsWriter - Write a vector into a buffer by first writing the vector length and then calling a callback on each passed value.
