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

Expand description

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

Fields

base: S

Unpacked base data

Implementations

source

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

source

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

source

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

source

fn get_tlv_data(&self) -> &[u8] ⓘ

Get the buffer containing all extension data

source

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

Unpack a portion of the TLV data as the desired type

source

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

Iterates through the TLV entries, returning only the types

source

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