Trait Implementations

impl<const N: usize> Clone for FixedBytes<N>

fn clone(&self) -> FixedBytes<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<const N: usize> Debug for FixedBytes<N>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<const N: usize> EventTopic for FixedBytes<N>

where ByteCount<N>: SupportedFixedBytes,

fn topic_preimage_length(_: &Self::RustType) -> usize

The number of bytes this type occupies in another topic’s preimage, usually a multiple of 32.

fn encode_topic_preimage(rust: &Self::RustType, out: &mut Vec<u8>)

Encodes this type as preimage bytes which are then hashed in complex types’ encode_topic.

fn encode_topic(rust: &Self::RustType) -> WordToken

Indexed event parameter encoding.

impl<const N: usize> SolType for FixedBytes<N>

where ByteCount<N>: SupportedFixedBytes,

const SOL_NAME: &'static str = ByteCount<N>::NAME

The name of this type in Solidity.

const ENCODED_SIZE: Option<usize> = _

The statically-known ABI-encoded size of the type.

const PACKED_ENCODED_SIZE: Option<usize> = _

The statically-known Non-standard Packed Mode ABI-encoded size of the type.

type RustType = FixedBytes<N>

The corresponding Rust type.

type Token<'a> = WordToken

The corresponding ABI token type.

fn valid_token(token: &Self::Token<'_>) -> bool

Returns true if the given token can be detokenized with this type.

fn detokenize(token: Self::Token<'_>) -> Self::RustType

Detokenize this type’s value from the given token.

const DYNAMIC: bool = _

Whether the ABI-encoded size is dynamic.

fn sol_type_name() -> Cow<'static, str>

👎Deprecated since 0.6.3: use SOL_NAME instead

Returns the name of this type in Solidity.

fn abi_encoded_size<E: ?Sized + SolTypeValue<Self>>(rust: &E) -> usize

Calculate the ABI-encoded size of the data, counting both head and tail words. For a single-word type this will always be 32.

fn type_check(token: &Self::Token<'_>) -> Result<()>

Returns an error if the given token cannot be detokenized with this type.

fn tokenize<E: ?Sized + SolTypeValue<Self>>(rust: &E) -> Self::Token<'_>

Tokenizes the given value into this type’s token.

fn eip712_data_word<E: ?Sized + SolTypeValue<Self>>(rust: &E) -> Word

Encode this data according to EIP-712 encodeData rules, and hash it if necessary.

fn abi_packed_encoded_size<E: ?Sized + SolTypeValue<Self>>(rust: &E) -> usize

Returns the length of this value when ABI-encoded in Non-standard Packed Mode.

fn abi_encode_packed_to<E: ?Sized + SolTypeValue<Self>>( rust: &E, out: &mut Vec<u8>, )

Non-standard Packed Mode ABI encoding.

fn abi_encode_packed<E: ?Sized + SolTypeValue<Self>>(rust: &E) -> Vec<u8>

Non-standard Packed Mode ABI encoding.

fn abi_encode<E: ?Sized + SolTypeValue<Self>>(rust: &E) -> Vec<u8>

Tokenizes and ABI-encodes the given value by wrapping it in a single-element sequence.

fn abi_decode(data: &[u8], validate: bool) -> Result<Self::RustType>

Decodes this type’s value from an ABI blob by interpreting it as a single-element sequence.

fn abi_decode_params<'de>( data: &'de [u8], validate: bool, ) -> Result<Self::RustType>

where Self::Token<'de>: TokenSeq<'de>,

Decodes this type’s value from an ABI blob by interpreting it as function parameters.

fn abi_decode_sequence<'de>( data: &'de [u8], validate: bool, ) -> Result<Self::RustType>

where Self::Token<'de>: TokenSeq<'de>,

Decodes this type’s value from an ABI blob by interpreting it as a sequence.
