Struct DynamicView 

pub struct DynamicView<'a, const N: usize> { /* private fields */ }

An inline dynamic view that caches offsets for O(1) field access.

Created by walking the prefix bytes once, then all accessors use the cached offsets.

Generic over N = number of dynamic fields.

Implementations

impl<'a, const N: usize> DynamicView<'a, N>

pub fn parse( data: &'a [u8], base_offset: usize, prefix_sizes: &[u8; N], ) -> Result<Self, ProgramError>

Parse dynamic fields starting at base_offset in data.

prefix_sizes indicates prefix type per field: 1 = u8, 2 = u16, 4 = u32.

pub fn field(&self, index: usize) -> &[u8]

Get the byte slice for dynamic field at index. O(1) after initial parse.

pub fn field_len(&self, index: usize) -> usize

Get the length of dynamic field at index.

pub fn field_as_str(&self, index: usize) -> Result<&str, ProgramError>

Try to interpret a dynamic field as a UTF-8 string.

pub fn total_dynamic_bytes(&self) -> usize

Total bytes consumed by all dynamic fields (including prefixes).
