Struct CharSetData

#[repr(C)]
pub struct CharSetData {
    pub num: c_int,
    pub leaves: Offset<Offset<CharSetLeaf>>,
    pub numbers: Offset<u16>,
    /* private fields */
}

A set of code points, in the raw serialized format.

Implementation details

This charset is implemented as a bunch of bitsets. Each bitset (a CharSetLeaf) has 256 bits, and so it represents the least significant byte of the codepoint. Associated to each leaf is a 16-bit offset, representing the next two least-significant bytes of the codepoint. (In particular, this can represent any subset of the numbers 0 through 0x00FFFFFF, which is big enough for the unicode range.)

Fields

num: c_int

Length of both of the following arrays

leaves: Offset<Offset<CharSetLeaf>>

Array of offsets to leaves. Each offset is relative to the start of the array, not the start of this struct!

numbers: Offset<u16>

Array having the same length as leaves, and storing the 16-bit offsets of each leaf.
