Struct SectionTable 

pub struct SectionTable { /* private fields */ }

The section table containing all section entries

Implementations

impl SectionTable

pub fn new() -> SectionTable

Create an empty section table

pub fn with_capacity(capacity: usize) -> SectionTable

Create with pre-allocated capacity

pub fn push(&mut self, entry: SectionEntry)

Add a section entry

pub fn len(&self) -> usize

Get number of sections

pub fn is_empty(&self) -> bool

Check if table is empty

pub fn get(&self, index: usize) -> Option<&SectionEntry>

Get entry by index

pub fn get_by_name_index(&self, name_index: u8) -> Option<&SectionEntry>

Get entry by its string-table name index

pub fn entries(&self) -> &[SectionEntry]

Get all entries

pub fn entries_by_priority(&self) -> Vec<&SectionEntry>

Get entries sorted by priority (highest first)

pub fn entries_within_budget(&self, budget: u16) -> Vec<&SectionEntry>

Get entries that fit within a token budget by dropping whole priority tiers from the tail (64, then 128, then 150–200). Original table order is preserved. Critical (255) entries always remain.

This is prefix truncation, not priority-first greedy: a hole in canonical order is not a rendering of this Content ID.

pub fn total_tokens(&self) -> u32

Calculate total token count

pub fn table_size(&self) -> usize

Calculate total size in bytes (for section table only)

pub fn write<W>(&self, writer: &mut W) -> Result<(), FafbError>

where W: Write,

Write section table to a byte buffer

pub fn to_bytes(&self) -> Result<Vec<u8>, FafbError>

Write section table to a new Vec<u8>

pub fn read<R>(reader: &mut R, count: usize) -> Result<SectionTable, FafbError>

where R: Read,

Read section table from a byte buffer

pub fn from_bytes(data: &[u8], count: usize) -> Result<SectionTable, FafbError>

Read section table from a byte slice

pub fn validate_bounds(&self, file_size: u32) -> Result<(), FafbError>

Validate all entries against file size

Trait Implementations
