Struct transferFromCall

pub struct transferFromCall {
    pub from: Address,
    pub to: Address,
    pub value: U256,
}

@dev Moves a value amount of tokens from from to to using the allowance mechanism. value is then deducted from the caller’s allowance.

Returns a boolean value indicating whether the operation succeeded.

Emits a {Transfer} event. Function with signature transferFrom(address,address,uint256) and selector 0x23b872dd.

function transferFrom(address from, address to, uint256 value) external returns (bool);

Fields

from: Address

to: Address

value: U256
