Struct spl_token_2022 :: pod :: PodCOption Copy item path

impl<T> PodCOption<T>
where T: Pod + Default,

pub const NONE: [u8; 4] = _

Represents that no value is stored in the option, like Option::None

pub const SOME: [u8; 4] = _

Represents that some value is stored in the option, like Option::Some(v)

pub fn none() -> Self

Create a PodCOption equivalent of Option::None

This could be made const by using std::mem::zeroed, but that would require unsafe code, which is prohibited at the crate level.

pub const fn some(value: T) -> Self

Create a PodCOption equivalent of Option::Some(value)

pub fn unwrap_or(self, default: T) -> T

Get the underlying value or another provided value if it isn’t set, equivalent of Option::unwrap_or

pub fn is_some(&self) -> bool

Checks to see if a value is set, equivalent of Option::is_some

pub fn is_none(&self) -> bool

Checks to see if no value is set, equivalent of Option::is_none

pub fn ok_or<E>(self, error: E) -> Result<T, E>

Converts the option into a Result, similar to Option::ok_or
