Implementations

impl Builder

pub fn with_root(data_words: u16, ptr_count: u16) -> (Self, StructBuilder)

A message whose root is a new struct of the given size.

pub fn set_bits(&mut self, s: StructBuilder, offset: u64, bits: u64, value: u64)

Store bits wide at bit offset of the data section.

pub fn set_u16(&mut self, s: StructBuilder, index: u64, v: u16)

pub fn set_u32(&mut self, s: StructBuilder, index: u64, v: u32)

pub fn set_u64(&mut self, s: StructBuilder, index: u64, v: u64)

pub fn set_bool(&mut self, s: StructBuilder, bit: u64, v: bool)

pub fn init_struct( &mut self, s: StructBuilder, index: u16, data_words: u16, ptr_count: u16, ) -> Result<StructBuilder>

A new struct stored in pointer index of s.

pub fn set_bytes( &mut self, s: StructBuilder, index: u16, bytes: &[u8], ) -> Result<()>

pub fn set_primitive_list( &mut self, s: StructBuilder, index: u16, size: ElementSize, values: &[u64], ) -> Result<()>

A primitive list in pointer index of s, from raw element bits.

pub fn init_struct_list( &mut self, s: StructBuilder, index: u16, len: u32, data_words: u16, ptr_count: u16, ) -> Result<Vec<StructBuilder>>

A composite list of len structs in pointer index of s.

pub fn init_pointer_list( &mut self, s: StructBuilder, index: u16, len: u32, ) -> Result<Vec<usize>>

A pointer list of len null pointers in pointer index of s; returns the slots.

pub fn slot_struct( &mut self, slot: usize, data_words: u16, ptr_count: u16, ) -> Result<StructBuilder>

Writers addressed by raw slot, for elements of a pointer list.

pub fn slot_bytes(&mut self, slot: usize, bytes: &[u8]) -> Result<()>
