Struct safe_token_2022::extension::StateWithExtensions

pub struct StateWithExtensions<'data, S: BaseState> {
    pub base: S,
    /* private fields */
}

Encapsulates immutable base state data (mint or account) with possible extensions

Fields

base: S

Unpacked base data

Implementations

impl<'data, S: BaseState> StateWithExtensions<'data, S>

pub fn unpack(input: &'data [u8]) -> Result<Self, ProgramError>

Unpack base state, leaving the extension data as a slice

Fails if the base state is not initialized.

Trait Implementations

impl<'a, S: BaseState> BaseStateWithExtensions<S> for StateWithExtensions<'a, S>

fn get_tlv_data(&self) -> &[u8]

Get the buffer containing all extension data

fn get_extension<V: Extension>(&self) -> Result<&V, ProgramError>

Unpack a portion of the TLV data as the desired type

fn get_extension_types(&self) -> Result<Vec<ExtensionType>, ProgramError>

Iterates through the TLV entries, returning only the types

fn get_first_extension_type( &self ) -> Result<Option<ExtensionType>, ProgramError>

Get just the first extension type, useful to track mixed initializations

impl<'data, S: Debug + BaseState> Debug for StateWithExtensions<'data, S>

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

Formats the value using the given formatter.

impl<'data, S: PartialEq + BaseState> PartialEq<StateWithExtensions<'data, S>> for StateWithExtensions<'data, S>

fn eq(&self, other: &StateWithExtensions<'data, S>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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