Struct FieldReader 

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

Field-based reader for structured data decoding

Implementations

impl<'a> FieldReader<'a>

pub fn new(data: &'a [u8]) -> Result<Self, DecodingError>

Create a new field reader

pub fn get_field(&self, field: u32) -> Option<&[u8]>

Get field data by number (used by envelope decoding)

pub fn has_field(&self, field: u32) -> bool

Check if field exists

pub fn field_numbers(&self) -> Vec<u32>

Get all field numbers (this is problematic without schema info)

pub fn read_uvarint_field( &self, field: u32, ) -> Result<Option<u64>, DecodingError>

Read uvarint from field (no length prefix)

pub fn read_varint_field( &self, field: u32, ) -> Result<Option<i64>, DecodingError>

Read varint from field (no length prefix)

Read big number from field

pub fn read_bool_field(&self, field: u32) -> Result<Option<bool>, DecodingError>

Read boolean from field

pub fn read_bytes_field( &self, field: u32, ) -> Result<Option<Vec<u8>>, DecodingError>

Read bytes from field (with length prefix)

pub fn read_string_field( &self, field: u32, ) -> Result<Option<String>, DecodingError>

Read string from field (with length prefix)

pub fn read_hash_field( &self, field: u32, ) -> Result<Option<[u8; 32]>, DecodingError>

Read hash from field
