Atomic parameter in the Airnode ABI

Variants

Address

parameter that embeds EVM address (160 bits, H160)

Fields

name: String

value: H160

Bool

(non-strict) parameter that embeds boolean value, stored as single Bytes32 value, encoded as bytes of “true” or “false” string

Fields

name: String

value: bool

Bytes

parameter that embeds array of bytes (dynamic size)

Fields

name: String

value: Vec<u8>

Bytes32

parameter that embeds single 256 bits value

Fields

name: String

value: U256

Date

(non-strict) parameter that embeds date value, stored as single Bytes32 value, encoded as bytes ISO-8601 string

Fields

name: String

year: i32

month: u32

day: u32

Int256

parameter that embeds signed 256 bits value (there is no type of I256 in Ethereum primitives)

Fields

name: String

value: U256

sign: i32

String

parameter that embeds UTF-8 string (dynamic size)

Fields

name: String

value: String

String32

(non-strict) parameter that embeds string as single Bytes32 value. The length of the string should not exceed 32 bytes it will be decoded correctly if this is non-empty valid Utf-8 string

Fields

name: String

value: String

Uint256

parameter that embeds unsigned 256 bits value

Fields

name: String

value: U256

Implementations

impl Param

pub fn get_name(&self) -> &str

returns name of the parameter

pub fn get_value(&self) -> String

returns value of the parameter as string (for debugging purposes only)

pub fn get_char(&self) -> char

returns character of the parameter for encoding

• Upper case letters refer to dynamically sized types
• Lower case letters refer to statically sized types
• String32 is encoded into Bytes32 in solidity

pub fn is_fixed_size(&self) -> bool

returns whether the size of the parameter value is fixed

Trait Implementations

impl Clone for Param

fn clone(&self) -> Param

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Param

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Param

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Param

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

Formats the value using the given formatter.

impl PartialEq for Param

fn eq(&self, other: &Param) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Param

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Param
