ParsedTransaction

Return type of parseTransaction.

Signature

pub fn ParsedTransaction(comptime T: type) type

Deinit

Cleans memory and destroys ArenaAllocator pointer.

Signature

pub fn deinit(self: @This()) void

ParseTransactionErrors

RlpDecodeErrors || error{ InvalidRecoveryId, InvalidTransactionType, NoSpaceLeft, InvalidLength }

ParseTransaction

Parses unsigned serialized transactions. Creates and arena to manage memory.
This is for the cases where we need to decode access list or if the serialized transaction contains data.

Example 
const tx: LondonTransactionEnvelope = .{
    .chainId = 1,
    .nonce = 0,
    .maxPriorityFeePerGas = 0,
    .maxFeePerGas = 0,
    .gas = 0,
    .to = null,
    .value = 0,
    .data = null,
    .accessList = &.{},
};
const min = try serialize.serializeTransaction(testing.allocator, .{ .london = tx }, null);
defer testing.allocator.free(min);
 
const parsed = try parseTransaction(testing.allocator, min);
defer parsed.deinit();

Signature

pub fn parseTransaction(allocator: Allocator, serialized: []const u8) ParseTransactionErrors!ParsedTransaction(TransactionEnvelope)

ParseTransactionLeaky

Parses unsigned serialized transactions. Recommend to use an arena or similar otherwise its expected to leak memory.

This is usefull for cases where the transaction object is expected to not have any allocated memory and it faster to decode because of it.

Example 
const tx: LondonTransactionEnvelope = .{
    .chainId = 1,
    .nonce = 0,
    .maxPriorityFeePerGas = 0,
    .maxFeePerGas = 0,
    .gas = 0,
    .to = null,
    .value = 0,
    .data = null,
    .accessList = &.{},
};
const min = try serialize.serializeTransaction(testing.allocator, .{ .london = tx }, null);
defer testing.allocator.free(min);
 
const parsed = try parseTransactionLeaky(testing.allocator, min);

Signature

pub fn parseTransactionLeaky(allocator: Allocator, serialized: []const u8) ParseTransactionErrors!TransactionEnvelope

ParseEip7702Transaction

ParseEip4844Transaction
