Struct CompressAndCloseMintAction 

#[repr(C)]
pub struct CompressAndCloseMintAction {
    pub idempotent: u8,
}

Action to compress and close a Mint Solana account. The compressed mint state is always preserved.

Requirements

• Mint must exist (mint_decompressed = true) - unless idempotent is set
• is_compressible() must return true (rent expired)
• Cannot be combined with DecompressMint in same instruction

Note

CompressAndCloseMint is permissionless - anyone can compress and close a Mint provided is_compressible() returns true. All lamports are returned to rent_sponsor.

Fields

idempotent: u8

If non-zero, succeed silently when Mint doesn’t exist or cannot be compressed. Useful for foresters to handle already-compressed mints without failing.

Implementations

impl CompressAndCloseMintAction

pub fn is_idempotent(&self) -> bool

Returns true if this action should succeed silently when:

• Mint doesn’t exist (already compressed)
• Mint cannot be compressed (rent not expired)

Trait Implementations

impl BorshDeserialize for CompressAndCloseMintAction

where u8: BorshDeserialize,

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

where u8: BorshSerialize,

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.
