Struct ContainerDecoder 

pub struct ContainerDecoder<'a> { /* private fields */ }

Helper for decoding containers with mixed fixed/variable fields.

Parses the fixed part to extract field slices and variable-field offsets.

Implementations

impl<'a> ContainerDecoder<'a>

pub fn new(bytes: &'a [u8], fixed_part_len: usize) -> Result<Self, DecodeError>

Create a new decoder. fixed_part_len is the expected total size of the fixed portion (sum of fixed field sizes + 4 bytes per variable field).

pub fn decode_fixed<T: SszDecode>(&mut self) -> Result<T, DecodeError>

Decode a fixed-size field at the current cursor position.

pub fn read_variable_offset(&mut self) -> Result<(), DecodeError>

Read a variable-field offset at the current cursor position. Call this for each variable field in order during the fixed-part pass.

pub fn decode_variable<T: SszDecode>(&mut self) -> Result<T, DecodeError>

Decode the next variable-length field. Must be called after all fixed-part reads (decode_fixed / read_variable_offset) are done.

pub fn finish_fixed(self) -> Result<(), DecodeError>

Verify there are no unconsumed bytes (for all-fixed containers).
