Struct postcard::flavors::HVec

pub struct HVec<B: ArrayLength<u8>>(_);

The HVec flavor is a wrapper type around a heapless::Vec. This is a stack allocated data structure, with a fixed maximum size and variable amount of contents.

Trait Implementations

impl<B: ArrayLength<u8>> Default for HVec<B>

fn default() -> Self

Returns the "default value" for a type.

impl<B: ArrayLength<u8>> Index<usize> for HVec<B>

type Output = u8

The returned type after indexing.

fn index(&self, idx: usize) -> &u8

Performs the indexing (container[index]) operation.

impl<B: ArrayLength<u8>> IndexMut<usize> for HVec<B>

fn index_mut(&mut self, idx: usize) -> &mut u8

Performs the mutable indexing (container[index]) operation.

impl<'a, B> SerFlavor for HVec<B> where
    B: ArrayLength<u8>, 

type Output = Vec<u8, B>

The Output type is what this flavor "resolves" to when the serialization is complete. For storage flavors, this is typically a concrete type. For modification flavors, this is typically a generic parameter for the storage flavor they are wrapped around.

fn try_extend(&mut self, data: &[u8]) -> Result<(), ()>

The try_extend() trait method can be implemented when there is a more efficient way of processing multiple bytes at once, such as copying a slice to the output, rather than iterating over one byte at a time.

fn try_push(&mut self, data: u8) -> Result<(), ()>

The try_push() trait method can be used to push a single byte to be modified and/or stored

fn release(self) -> Result<Vec<u8, B>, ()>

The release() trait method finalizes the modification or storage operation, and resolved into the type defined by SerFlavor::Output associated type.
