Struct CompressibleParams 

pub struct CompressibleParams {
    pub token_account_version: TokenDataVersion,
    pub pre_pay_num_epochs: u8,
    pub lamports_per_write: Option<u32>,
    pub compress_to_account_pubkey: Option<CompressToPubkey>,
    pub compressible_config: Pubkey,
    pub rent_sponsor: Pubkey,
    pub compression_only: bool,
}

Parameters for creating compressible ctoken accounts.

Compressible accounts have sponsored rent and can be compressed to compressed token accounts when their lamports balance is insufficient.

Default values are:

• 24 hours rent
• lamports for 3 hours rent (paid on transfer when account rent is insufficient to cover the next 2 epochs)
• Protocol rent sponsor
• TokenDataVersion::ShaFlat token data hashing (only sha is supported for compressible accounts)

Example

use light_token::instruction::CompressibleParams;

let params = CompressibleParams::new();

Fields

token_account_version: TokenDataVersion

pre_pay_num_epochs: u8

lamports_per_write: Option<u32>

Number of lamports transferred on a write operation (eg transfer) when account rent is insufficient to cover the next 2 rent-epochs. Default: 766 lamports for 3 hours rent. These lamports keep the ctoken account perpetually funded when used.

compress_to_account_pubkey: Option<CompressToPubkey>

compressible_config: Pubkey

rent_sponsor: Pubkey

compression_only: bool

Implementations

impl CompressibleParams

pub fn new() -> Self

Creates a new CompressibleParams with default values.

• 24 hours rent
• 3 hours top up (paid on transfer when account rent is insufficient to cover the next 2 epochs)
• Protocol rent sponsor
• TokenDataVersion::ShaFlat token data hashing (only sha is supported for compressible accounts)

pub fn default_ata() -> Self

Creates default params for ATAs (compression_only = true). ATAs are always compression_only.

pub fn compress_to_pubkey(self, compress_to: CompressToPubkey) -> Self

Sets the destination pubkey for compression.

Trait Implementations

impl Clone for CompressibleParams

fn clone(&self) -> CompressibleParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompressibleParams

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

Formats the value using the given formatter.

impl Default for CompressibleParams

fn default() -> Self

Returns the “default value” for a type.
