Atomic parameter in the Airnode ABI

Variants

Address

Fields

name: String

value: H160

parameter that embeds EVM address (160 bits, H160)

Bool

Fields

name: String

value: bool

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

Bytes

Fields

name: String

value: Vec<u8>

parameter that embeds array of bytes (dynamic size)

Bytes32

Fields

name: String

value: U256

parameter that embeds single 256 bits value

Date

Fields

name: String

year: i32

month: u32

day: u32

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

Int256

Fields

name: String

value: U256

sign: i32

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

String

Fields

name: String

value: String

parameter that embeds UTF-8 string (dynamic size)

String32

Fields

name: String

value: String

(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

Uint256

Fields

name: String

value: U256

parameter that embeds unsigned 256 bits value

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

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 copy 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>,

impl Display for Param

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

Formats the value using the given formatter.

impl PartialEq<Param> for Param

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
