Struct write_fonts::TableWriter

pub struct TableWriter { /* private fields */ }

An object that manages a collection of serialized tables.

This handles deduplicating objects and tracking offsets.

Implementations

impl TableWriter

pub fn write_slice(&mut self, bytes: &[u8])

Write raw bytes into this table.

The caller is responsible for ensuring bytes are in big-endian order.

pub fn write_offset(&mut self, obj: &dyn FontWrite, width: usize)

Create an offset to another table.

The width argument is the size in bytes of the offset, e.g. 2 for an Offset16, and 4 for an Offset32.

The provided table will be serialized immediately, and the position of the offset within the current table will be recorded. Offsets are resolved when the root table object is serialized, at which point we overwrite each recorded offset position with the final offset of the appropriate table.

Trait Implementations

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

impl Default for TableWriter

fn default() -> Self
