Struct capnp::message::Builder

pub struct Builder<A> where
    A: Allocator,  { /* fields omitted */ }

A container used to build a message.

Methods

impl<A> Builder<A> where     A: Allocator,

pub fn new(allocator: A) -> Self

pub fn init_root<'a, T: FromPointerBuilder<'a>>(&'a mut self) -> T

Initializes the root as a value of the given type.

pub fn get_root<'a, T: FromPointerBuilder<'a>>(&'a mut self) -> Result<T>

Gets the root, interpreting it as the given type.

pub fn get_root_as_reader<'a, T: FromPointerReader<'a>>(&'a self) -> Result<T>

pub fn set_root<To, From: SetPointerBuilder<To>>(     &mut self,     value: From ) -> Result<()>

Sets the root to a deep copy of the given value.

pub fn set_root_canonical<To, From: SetPointerBuilder<To>>(     &mut self,     value: From ) -> Result<()>

Sets the root to a canonicalized version of value. If this was the first action taken on this Builder, then a subsequence call to get_segments_for_output() should return a single segment, containing the full canonicalized message.

pub fn get_segments_for_output<'a>(&'a self) -> OutputSegments<'a>

pub fn into_reader(self) -> Reader<Builder<A>>

impl Builder<HeapAllocator>

pub fn new_default() -> Builder<HeapAllocator>

Trait Implementations

impl<A, T> From<Builder<A>> for TypedReader<Builder<A>, T> where     A: Allocator,     T: for<'a> Owned<'a>,

fn from(message: Builder<A>) -> TypedReader<Builder<A>, T>

Performs the conversion.

impl<A> Send for Builder<A> where     A: Send + Allocator,

impl<A> ReaderSegments for Builder<A> where     A: Allocator,

fn get_segment<'a>(&'a self, id: u32) -> Option<&'a [Word]>

Gets the segment with index idx. Returns None if idx is out of range.

fn len(&self) -> usize

Gets the number of segments.
