Struct evm_coder::abi::AbiWriter

pub struct AbiWriter { /* private fields */ }

Writer for RLP encoded data

Implementations

impl AbiWriter

pub fn new() -> Self

Initialize internal buffers for output data, assuming no padding required

pub fn new_dynamic(is_dynamic: bool) -> Self

Initialize internal buffers with data size

pub fn new_call(method_id: u32) -> Self

Initialize internal buffers, inserting method selector at beginning

pub fn address(&mut self, address: &H160)

Write H160 to end of buffer

pub fn bool(&mut self, value: &bool)

Write bool to end of buffer

pub fn uint8(&mut self, value: &u8)

Write u8 to end of buffer

pub fn uint32(&mut self, value: &u32)

Write u32 to end of buffer

pub fn uint64(&mut self, value: &u64)

Write u64 to end of buffer

pub fn uint128(&mut self, value: &u128)

Write u128 to end of buffer

pub fn uint256(&mut self, value: &U256)

Write U256 to end of buffer

pub fn write_usize(&mut self, value: &usize)

👎Deprecated: dangerous, as usize may have different width in wasm and native execution

Write usize to end of buffer

pub fn write_subresult(&mut self, result: Self)

Append recursive data, writing pending offset at end of buffer

pub fn string(&mut self, value: &str)

Append recursive str at end of buffer

pub fn bytes(&mut self, value: &[u8])

Append recursive [[u8]] at end of buffer

pub fn bytes_padleft(&mut self, block: &[u8])

Write [bytes] to end of buffer

pub fn finish(self) -> Vec<u8>

Finish writer, concatenating all internal buffers

Trait Implementations

impl Default for AbiWriter

fn default() -> AbiWriter
