Struct evm_coder::abi::AbiReader

pub struct AbiReader<'i> { /* private fields */ }

View into RLP data, which provides method to read typed items from it

Implementations

impl<'i> AbiReader<'i>

pub fn new(buf: &'i [u8]) -> Self

Start reading RLP buffer, assuming there is no padding bytes

pub fn new_call(buf: &'i [u8]) -> Result<(Bytes4, Self)>

Start reading RLP buffer, parsing first 4 bytes as selector

Errors

Fails if provided buffer has not enough length for selector+data

pub fn address(&mut self) -> Result<H160>

Read H160 at current position, then advance

pub fn bool(&mut self) -> Result<bool>

Read bool at current position, then advance

pub fn bytes4(&mut self) -> Result<[u8; 4]>

Read [[u8; 4]] at current position, then advance

pub fn bytes(&mut self) -> Result<Vec<u8>>

Read Vec<u8> at current position, then advance

pub fn string(&mut self) -> Result<String>

Read String at current position, then advance

pub fn uint8(&mut self) -> Result<u8>

Read u8 at current position, then advance

pub fn uint32(&mut self) -> Result<u32>

Read u32 at current position, then advance

pub fn uint128(&mut self) -> Result<u128>

Read u128 at current position, then advance

pub fn uint256(&mut self) -> Result<U256>

Read U256 at current position, then advance

pub fn uint64(&mut self) -> Result<u64>

Read u64 at current position, then advance

pub fn read_usize(&mut self) -> Result<usize>

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

Read usize at current position, then advance

pub fn subresult(&mut self, size: Option<usize>) -> Result<AbiReader<'i>>

Slice recursive buffer, advance one word for buffer offset If size is None then offsets evals from internal buffer.

Errors

Fails on bad subresult offset

pub fn bytes_read(&mut self, size: usize)

Notify about readed data portion.

pub fn is_finished(&self) -> bool

Is this parser reached end of buffer?

Trait Implementations

impl<'i> Clone for AbiReader<'i>

fn clone(&self) -> AbiReader<'i>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
