Trait postcard::flavors::SerFlavor[−][src]

pub trait SerFlavor {
    type Output;
    fn try_push(&mut self, data: u8) -> Result<(), ()>;

    fn release(self) -> Result<Self::Output, ()>;

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

    fn try_push_varint_usize(&mut self, data: &VarintUsize) -> Result<(), ()> { ... }
}

The SerFlavor trait acts as a combinator/middleware interface that can be used to pass bytes through storage or modification flavors. See the module level documentation for more information and examples.

Associated Types

type Output[src]

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.

Required methods

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

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

fn release(self) -> Result<Self::Output, ()>[src]

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

Provided methods

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

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_varint_usize(&mut self, data: &VarintUsize) -> Result<(), ()>[src]

The try_push_varint_usize() trait method can be used to push a VarintUsize. The default implementation uses try_extend() to process the encoded VarintUsize bytes, which is likely the desired behavior for most circumstances.
