View Source Web3.Type.Data (web3 v0.1.6)

The Elixir-native representation of t:EthereumJSONRPC.data/0.

t:EthereumJSONRPC.data/0 is an unpadded hexadecimal number with 0 or more digits. Each pair of digits maps directly to a byte in the underlying binary representation. When interpreted as a number, it should be treated as big-endian.

Types

t()

A variable-byte-length binary, wrapped in a struct, so that it can use protocols.

Functions

cast(data)

Casts term to t/0.

dump(arg1)

Dumps the binary data to :binary (bytea) format used in database.

embed_as(_)

Callback implementation for Ecto.Type.embed_as/1.

equal?(term1, term2)

Callback implementation for Ecto.Type.equal?/2.

load(bytes)

Loads the binary data from the database.

to_iodata(data)

Converts the t/0 to iodata representation written efficiently to users.

to_string(data)

Converts the t/0 to string representation shown to users.

type()

The underlying database type: :binary.

@type t() :: %Web3.Type.Data{bytes: <<_::_*8>>}

cast(data)

View Source 
@spec cast(term()) :: {:ok, t()} | :error

Casts term to t/0.

An empty t/0 will pass through unchanged

iex> Web3.Type.Data.cast(%Web3.Type.Data{bytes: <<>>})
{:ok, %Web3.Type.Data{bytes: <<>>}}

An empty t/0 is presented as 0x in Ethereum JSONRPC.

iex> Web3.Type.Data.cast("0x")
{:ok, %Web3.Type.Data{bytes: <<>>}}

Hashes can be represented as Web3.Type.Data, but it is better to use Web3.Type.Hash.Full or Web3.Type.Hash.Address.

A hexadecimal number MUST be byte-aligned. If it has an odd number of digits, then it is only nibble-aligned and can't a valid t:EthereumJSONRPC.data/0, which MUST be in bytes.

dump(arg1)

View Source 
@spec dump(term()) :: {:ok, binary()} | :error

Dumps the binary data to :binary (bytea) format used in database.

If the field from the struct is t/0, then it succeeds.

iex> Web3.Type.Data.dump(
...>   %Web3.Type.Data{
...>     bytes: <<>>
...>   }
...> )
{:ok, <<>>}

If the field is from a different struct, :error is returned.

...>   %Web3.Type.Hash{
...>     byte_count: 20,
...>     bytes: <<0x5aAeb6053F3E94C9b9A09f33669435E7Ef1BeAed :: big-integer-size(20)-unit(8)>>
