Implementations

source

impl<S: BaseState> StateWithExtensionsOwned<S>

source

pub fn unpack(input: Vec<u8>) -> Result<Self, ProgramError>

Unpack a portion of the TLV data as the desired type

source

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

Iterates through the TLV entries, returning only the types
