Enum Erc20Call 

pub enum Erc20Call {
    Transfer {
        to: [u8; 20],
        amount: U256,
    },
    Approve {
        spender: [u8; 20],
        amount: U256,
    },
    TransferFrom {
        from: [u8; 20],
        to: [u8; 20],
        amount: U256,
    },
}

Parsed ERC-20 function call.

Represents one of the three primary ERC-20 functions with their decoded parameters.

Examples

use txgate_chain::erc20::Erc20Call;
use alloy_primitives::U256;

let transfer = Erc20Call::Transfer {
    to: [0x12; 20],
    amount: U256::from(1_000_000u64),
};

let approve = Erc20Call::Approve {
    spender: [0x34; 20],
    amount: U256::MAX, // Unlimited approval
};

let transfer_from = Erc20Call::TransferFrom {
    from: [0x12; 20],
    to: [0x34; 20],
    amount: U256::from(500_000u64),
};

Variants

Transfer

ERC-20 transfer(address to, uint256 amount) call.

Transfers amount tokens from the caller to to.

Fields

to: [u8; 20]

Recipient address (20 bytes).

amount: U256

Amount of tokens to transfer (in smallest unit).

Approve

ERC-20 approve(address spender, uint256 amount) call.

Approves spender to transfer up to amount tokens on behalf of the caller.

Fields

spender: [u8; 20]

Spender address authorized to transfer tokens (20 bytes).

amount: U256

Maximum amount the spender can transfer.

TransferFrom

ERC-20 transferFrom(address from, address to, uint256 amount) call.

Transfers amount tokens from from to to, using the caller’s allowance.

Fields

from: [u8; 20]

Source address to transfer from (20 bytes).

to: [u8; 20]

Destination address to transfer to (20 bytes).

amount: U256

Amount of tokens to transfer (in smallest unit).

Implementations

impl Erc20Call

pub const fn recipient(&self) -> &[u8; 20]

Returns the actual recipient address for this call.

For Transfer and TransferFrom, returns the to address. For Approve, returns the spender address.

pub const fn amount(&self) -> &U256

Returns the amount involved in this call.

pub const fn is_transfer(&self) -> bool

Returns true if this is a transfer operation (Transfer or TransferFrom).

pub const fn is_approval(&self) -> bool

Returns true if this is an approval operation.

Trait Implementations

impl Clone for Erc20Call

fn clone(&self) -> Erc20Call

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Erc20Call

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

Formats the value using the given formatter.

impl PartialEq for Erc20Call

fn eq(&self, other: &Erc20Call) -> 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.
