pub fn global() -> ControlInfo

Create global control information for the start of the HDT file

pub fn header(length: usize) -> ControlInfo

Create control information for the header

pub fn four_sect_dict() -> ControlInfo

Create control information for the four section dictionary

pub fn bitmap_triples(order: u32, num_triples: u32) -> ControlInfo

Create control information for BitmapTriples

pub fn read<R: BufRead>(reader: &mut R) -> Result<Self>

Read and verify control information.

pub fn write(&self, write: &mut impl Write) -> Result<()>

Trait Implementations

impl Clone for ControlInfo

fn clone(&self) -> ControlInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ControlInfo

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

Formats the value using the given formatter.

impl Default for ControlInfo

fn default() -> ControlInfo

Returns the “default value” for a type.

impl Eq for ControlInfo

impl PartialEq for ControlInfo

fn eq(&self, other: &ControlInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
