Struct AbiParser

pub struct AbiParser {
    pub structs: HashMap<String, SolStruct>,
    pub struct_tuples: HashMap<String, Vec<ParamType>>,
    pub function_params: HashMap<(String, String), String>,
    pub event_params: HashMap<(String, usize), String>,
    pub outputs: HashMap<String, Vec<String>>,
}

A parser that turns a “human readable abi” into a Abi

Fields

structs: HashMap<String, SolStruct>

solidity structs

struct_tuples: HashMap<String, Vec<ParamType>>

solidity structs as tuples

function_params: HashMap<(String, String), String>

(function name, param name) -> struct which are the identifying properties we get the name from ethabi.

event_params: HashMap<(String, usize), String>

(event name, idx) -> struct which are the identifying properties we get the name from ethabi.

Note: we need to map the index of the event here because events can contain nameless inputs

outputs: HashMap<String, Vec<String>>

(function name) -> Vec<structs> all structs the function returns

Implementations

impl AbiParser

pub fn parse_str(&mut self, s: &str) -> Result<Abi, ParseError>

Parses a “human readable abi” string

Example

let abi = AbiParser::default().parse_str("[
        function setValue(string)
        function getValue() external view returns (string)
        event ValueChanged(address indexed author, string oldValue, string newValue)
    ]").unwrap();

pub fn parse(&mut self, input: &[&str]) -> Result<Abi, ParseError>

Parses a “human readable abi” string vector

Example

use ethers_core::abi::AbiParser;

let abi = AbiParser::default().parse(&[
    "function x() external view returns (uint256)",
]).unwrap();

pub fn with_structs(structs: Vec<SolStruct>) -> Self

Link additional structs for parsing

pub fn parse_event(&mut self, s: &str) -> Result<Event, ParseError>

Parses a solidity event declaration from event <name> (args*) anonymous?

pub fn parse_function(&mut self, s: &str) -> Result<Function, ParseError>

Returns the parsed function from the input string

Example

use ethers_core::abi::AbiParser;
let f = AbiParser::default()
    .parse_function("bar(uint256 x, uint256 y, address addr)").unwrap();

pub fn parse_constructor(&self, s: &str) -> Result<Constructor, ParseError>

Trait Implementations

impl Default for AbiParser

fn default() -> Self

Returns the “default value” for a type.
