Trait LightPreInit 

pub trait LightPreInit<'info, P> {
    // Required method
    fn light_pre_init(
        &mut self,
        remaining_accounts: &[AccountInfo<'info>],
        params: &P,
    ) -> Result<bool, LightSdkError>;
}

Trait for pre-initialization operations (mint creation).

This is generated by #[derive(LightFinalize)] when #[light_account(init)] fields exist. Called at the START of an instruction to write mint creation to CPI context.

The mints are written to CPI context but NOT executed yet - execution happens in light_finalize() at the end, allowing the shared proof to cover both mints and PDAs.

Type Parameters

• 'info - The account info lifetime
• P - The instruction params type (from #[instruction(params: P)])

Required Methods

fn light_pre_init( &mut self, remaining_accounts: &[AccountInfo<'info>], params: &P, ) -> Result<bool, LightSdkError>

Execute pre-initialization operations (mint creation).

This writes mint creation operations to CPI context. The actual execution with proof happens in light_finalize().

Arguments

• remaining_accounts - The remaining accounts from the context, used for CPI
• params - The instruction parameters containing compression data

Returns

true if mints were written to CPI context and light_finalize should execute with CPI context. false if no mints exist and normal flow should proceed.
