Pass tuple enum to instruction data

[rocalex]

I pass custom struct including tuple enum to instruction:

#[derive(Debug, AnchorSerialize, AnchorDeserialize)]
pub enum FeedValue {
    Boolean(bool),
    U8(u8),
    U16(u16),
    U32(u32),
    U64(u64),
    U128(u128),
}

#[derive(Debug, AnchorSerialize, AnchorDeserialize)]
pub struct Feed {
    /// The value that is stored within a single feed. In most cases, intermediate
    /// nodes or non-leaf feeds will be None (although some may decide to have a
    /// summary value for their children), and leaf feeds will have concrete values.
    pub value: Option<FeedValue>,
}

#[program]
pub mod my_program {
    use super::*;

    pub fn create(ctx: Context<Create>, feed: Feed) -> Result<()> {
        Ok(())
    }
}

and I've got this error:

Error: Tuple enum variants not yet implemented.

How to fix it?

See the error Error: Tuple enum variants not yet implemented.. Please use a struct enum variant for now.

You might want to check out anchor-client-gen - it has tuple enum support.

[acheroncrypto]

Using tuple enum as an argument was implemented in #2185 and inside account data in #2601.
