Class BcsReader

Class used for reading BCS data chunk by chunk. Meant to be used by some wrapper, which will make sure that data is valid and is matching the desired format.

Example

// data for this example is:
// { a: u8, b: u32, c: bool, d: u64 }

let reader = new BcsReader("647f1a060001ffffe7890423c78a050102030405");
let field1 = reader.read8();
let field2 = reader.read32();
let field3 = reader.read8() === '1'; // bool
let field4 = reader.read64();
// ....

Reading vectors is another deal in bcs. To read a vector, you first need to read
its length using {@link readULEB}. Here's an example:
Copy

Example

// data encoded: { field: [1, 2, 3, 4, 5] }
let reader = new BcsReader("050102030405");
let vec_length = reader.readULEB();
let elements = [];
for (let i = 0; i < vec_length; i++) {
  elements.push(reader.read8());
}
console.log(elements); // [1,2,3,4,5]
Copy

Param: data

HEX-encoded data (serialized BCS)
