Struct ethers_solc::remappings::Remapping

pub struct Remapping {
    pub name: String,
    pub path: String,
}

The solidity compiler can only reference files that exist locally on your computer. So importing directly from GitHub (as an example) is not possible.

Let’s imagine you want to use OpenZeppelin’s amazing library of smart contracts, @openzeppelin/contracts-ethereum-package:

pragma solidity 0.5.11;

import "@openzeppelin/contracts-ethereum-package/contracts/math/SafeMath.sol";

contract MyContract {
    using SafeMath for uint256;
    ...
}

When using solc, you have to specify the following:

“prefix” = the path that’s used in your smart contract, i.e. “@openzeppelin/contracts-ethereum-package” “target” = the absolute path of OpenZeppelin’s contracts downloaded on your computer

The format looks like this: solc prefix=target ./MyContract.sol

solc –bin @openzeppelin/contracts-ethereum-package=/Your/Absolute/Path/To/@openzeppelin/ contracts-ethereum-package ./MyContract.sol

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

Performs copy-assignment from source.

impl Debug for Remapping

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Remapping

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where

impl FromStr for Remapping

type Err = RemappingError

The associated error which can be returned from parsing.

fn from_str(remapping: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Ord for Remapping

fn cmp(&self, other: &Remapping) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Remapping> for Remapping

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

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

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

This method tests for !=.
