Struct InterfaceMint 

pub struct InterfaceMint<'a> {
    pub kind: TokenProgramKind,
    /* private fields */
}

Polymorphic SPL Token / Token-2022 mint overlay.

SPL Mint and Token-2022 base mint share the same first 82 bytes (mint authority COption, supply, decimals, is_init flag, freeze authority COption). Token-2022 extension bytes begin at offset 165; this wrapper exposes only the base layout. Use crate::token2022_ext helpers for extension parsing.

Fields

kind: TokenProgramKind

Which program owns the mint.

Implementations

impl<'a> InterfaceMint<'a>

pub fn from_data( data: &'a [u8], kind: TokenProgramKind, ) -> Result<InterfaceMint<'a>, ProgramError>

Wrap a previously-borrowed mint body. Caller verifies kind using TokenProgramKind::for_account.

pub fn data(&self) -> &'a [u8]

The raw mint bytes.

pub fn supply(&self) -> Result<u64, ProgramError>

The mint supply.

pub fn decimals(&self) -> Result<u8, ProgramError>

The mint decimals.

pub fn authority(&self) -> Result<Option<&'a Address>, ProgramError>

The mint authority, if set.

pub fn freeze_authority(&self) -> Result<Option<&'a Address>, ProgramError>

The freeze authority, if set.

pub fn assert_initialized(&self) -> Result<(), ProgramError>

Convenience: assert the mint is initialised.

Trait Implementations

impl<'a> Clone for InterfaceMint<'a>

fn clone(&self) -> InterfaceMint<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for InterfaceMint<'a>

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

Formats the value using the given formatter.
