Element that can be decoded from a CDF file

Required Methods

fn try_from_buffer_in_place<'a, 'b>( &'a mut self, ctx: &DecoderContext<'a>, buf: &'b [u8], ) -> Result<()>

Deserialize the type from a given buffer

As in EncodableElement::to_buffer the implementor of this function can assume the buffer is big enough to contain all the required bytes.

Provided Methods

fn try_from_buffer<'b>(ctx: &DecoderContext<'_>, buf: &'b [u8]) -> Result<Self>

Create a new instance of the type from the provided buffer

fn try_decode_in_place<'a, 'b>( &mut self, ctx: &DecoderContext<'a>, buf: &'b [u8], ) -> Result<&'b [u8]>

Write an element from the buffer, and return the remainder bytes

Assume its inside a validate buffer context

fn try_decode<'a, 'b>( ctx: &DecoderContext<'a>, buf: &'b [u8], ) -> Result<(Self, &'b [u8])>

Write an element from the buffer, and return the remainder bytes

Assume its inside a validate buffer context

fn try_from_reader<R>(ctx: &DecoderContext<'_>, reader: R) -> Result<Self>

where R: Read,

Fetch a new element from a context

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
