Struct spl_type_length_value::state::TlvStateOwned

pub struct TlvStateOwned { /* private fields */ }

Encapsulates owned TLV data

Implementations

impl TlvStateOwned

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

Unpacks TLV state data

Fails if no state is initialized or if data is too small

Trait Implementations

impl Debug for TlvStateOwned

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

Formats the value using the given formatter.

impl PartialEq for TlvStateOwned

fn eq(&self, other: &TlvStateOwned) -> 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.

impl TlvState for TlvStateOwned

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

Get the full buffer containing all TLV data

fn get_value_with_repetition<V: SplDiscriminate + Pod>( &self, repetition_number: usize, ) -> Result<&V, ProgramError>

Unpack a portion of the TLV data as the desired Pod type for the entry number specified

fn get_first_value<V: SplDiscriminate + Pod>(&self) -> Result<&V, ProgramError>

Unpack a portion of the TLV data as the desired Pod type for the first entry found

fn get_variable_len_value_with_repetition<V: SplDiscriminate + VariableLenPack>( &self, repetition_number: usize, ) -> Result<V, ProgramError>

Unpacks a portion of the TLV data as the desired variable-length type for the entry number specified

fn get_first_variable_len_value<V: SplDiscriminate + VariableLenPack>( &self, ) -> Result<V, ProgramError>

Unpacks a portion of the TLV data as the desired variable-length type for the first entry found

fn get_bytes_with_repetition<V: SplDiscriminate>( &self, repetition_number: usize, ) -> Result<&[u8], ProgramError>

Unpack a portion of the TLV data as bytes for the entry number specified

fn get_first_bytes<V: SplDiscriminate>(&self) -> Result<&[u8], ProgramError>

Unpack a portion of the TLV data as bytes for the first entry found

fn get_discriminators(&self) -> Result<Vec<ArrayDiscriminator>, ProgramError>

Iterates through the TLV entries, returning only the types

fn get_base_len() -> usize

Get the base size required for TLV data
