Struct flatbuffers::Table

pub struct Table { /* fields omitted */ }

Table provides functions to read Flatbuffer data.

Methods

impl Table

fn from_offset(buffer: Rc<Vec<u8>>, pos: usize) -> Table

Create a table using from a slice using data starting at pos. First UOffsetT should indicate the offset from the root of the table to the begining of the object.

In the following example pos should be 0: 16, 0, 0, 0, // root of table: points to object <--------- 0, 0, // padding 10, 0, // vtable bytes 8, 0, // size of object 7, 0, // start of value 0 6, 0, // start of value 1 5, 0, // start of value 2 10, 0, 0, 0, // start of object..ie. vtable offset 0, // padding 77, // value 2 66, // value 1 55, // value 0

fn with_pos(buffer: Rc<Vec<u8>>, pos: usize) -> Table

Create a table for an object. pos should be the offset to the first byte of useable data.

In the following example pos should be 16: 16, 0, 0, 0, // root of table: points to object 0, 0, // padding 10, 0, // vtable bytes 8, 0, // size of object 7, 0, // start of value 0 6, 0, // start of value 1 5, 0, // start of value 2 10, 0, 0, 0, // start of object..ie. vtable offset <--------- 0, // padding 77, // value 2 66, // value 1 55, // value 0
