Struct ApproveChecked 

pub struct ApproveChecked {
    pub amount: u64,
    pub decimals: u8,
}

Approves a delegate. A delegate is given the authority over tokens on behalf of the source account’s owner. This instruction differs from Approve in that the token mint and decimals value is checked by the caller. This may be useful when creating transactions offline or within a hardware wallet.

Fields

amount: u64

The amount of tokens the delegate is approved for.

decimals: u8

Expected number of base 10 digits to the right of the decimal place.

Implementations

impl Clone for ApproveChecked

fn clone(&self) -> ApproveChecked

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ApproveChecked

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

Formats the value using the given formatter.

impl PartialEq for ApproveChecked

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