Struct Mint 

#[repr(C)]
pub struct Mint {
    pub base: BaseMint,
    pub metadata: MintMetadata,
    pub reserved: [u8; 16],
    pub account_type: u8,
    pub compression: CompressionInfo,
    pub extensions: Option<Vec<ExtensionStruct>>,
}

Fields

base: BaseMint

metadata: MintMetadata

reserved: [u8; 16]

Reserved bytes (16 bytes) for T22 layout compatibility. Positions account_type at offset 165: 82 (BaseMint) + 67 (metadata) + 16 (reserved) = 165.

account_type: u8

Account type discriminator at byte offset 165 (1 = Mint, 2 = Account)

compression: CompressionInfo

Compression info embedded directly in the mint

extensions: Option<Vec<ExtensionStruct>>

Implementations

impl Mint

pub fn hash(&self) -> Result<[u8; 32], TokenError>

pub fn from_account_info_checked( account_info: &AccountInfo, ) -> Result<Self, TokenError>

Deserialize a Mint from a Solana account with validation.

Checks:

1. Account is owned by the specified program
2. Account is initialized (BaseMint.is_initialized == true)

Note: Mint accounts follow SPL token mint pattern (no discriminator). Validation is done via owner check + PDA derivation (caller responsibility).

pub fn is_mint_account(&self) -> bool

Checks if account_type matches Mint discriminator value

impl Mint

pub fn zero_copy_at_checked( bytes: &[u8], ) -> Result<(ZMint<'_>, &[u8]), TokenError>

Zero-copy deserialization with initialization and account_type check. Returns an error if:

• Account is not initialized (is_initialized == false)
• Account type is not ACCOUNT_TYPE_MINT (byte 165 != 1)

pub fn zero_copy_at_mut_checked( bytes: &mut [u8], ) -> Result<(ZMintMut<'_>, &mut [u8]), TokenError>

Mutable zero-copy deserialization with initialization and account_type check. Returns an error if:

• Account is not initialized (is_initialized == false)
• Account type is not ACCOUNT_TYPE_MINT

Trait Implementations

impl BorshDeserialize for Mint

where BaseMint: BorshDeserialize, MintMetadata: BorshDeserialize, [u8; 16]: BorshDeserialize, u8: BorshDeserialize, CompressionInfo: BorshDeserialize, Option<Vec<ExtensionStruct>>: 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.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

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

where R: Read,

impl BorshSerialize for Mint

where BaseMint: BorshSerialize, MintMetadata: BorshSerialize, [u8; 16]: BorshSerialize, u8: BorshSerialize, CompressionInfo: BorshSerialize, Option<Vec<ExtensionStruct>>: 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.

impl Clone for Mint

fn clone(&self) -> Mint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mint

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

Formats the value using the given formatter.

impl Default for Mint

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Mint

fn eq(&self, other: &Mint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> TryFrom<&ZMintInstructionData<'a>> for Mint

type Error = TokenError

The type returned in the event of a conversion error.

fn try_from( instruction_data: &ZMintInstructionData<'a>, ) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Mint> for MintInstructionData

type Error = TokenError

The type returned in the event of a conversion error.

fn try_from(mint: Mint) -> Result<Self, Self::Error>

Performs the conversion.

impl<'a> ZeroCopyAt<'a> for Mint

type ZeroCopyAt = ZMint<'a>

type ZeroCopyAtMut = ZMintMut<'a>

fn zero_copy_at_mut( bytes: &'a mut [u8], ) -> Result<(Self::ZeroCopyAtMut, &'a mut [u8]), ZeroCopyError>

impl<'a> ZeroCopyNew<'a> for Mint

type ZeroCopyConfig = MintConfig

Configuration type needed to initialize this type

type Output = ZMintMut<'a>

Output type - the mutable zero-copy view of this type

fn byte_len(config: &Self::ZeroCopyConfig) -> Result<usize, ZeroCopyError>
