Struct HelloAck 

pub struct HelloAck<'a> {
    pub abi_major: u16,
    pub abi_minor: u16,
    pub required: CapabilitySet,
    pub optional: CapabilitySet,
    pub decoder_id: &'a str,
}

The decoder answering the host.

Fields

abi_major: u16

The major ABI version the decoder was built against.

abi_minor: u16

The minor ABI version the decoder was built against.

required: CapabilitySet

What the decoder cannot run without. If the host does not offer all of these, the two sides stop here.

optional: CapabilitySet

What the decoder will use if it is there and do without if it is not.

decoder_id: &'a str

A name for the decoder, for logs and error messages. Not interpreted.

Implementations

impl<'a> HelloAck<'a>

pub const VERSION: u16 = 1

The layout version of this record.

pub fn encode(&self, w: &mut Writer<'_>) -> Result<()>

Writes the record.

Errors

Returns Error::BufferFull if the buffer runs out.

pub fn decode(version: u16, p: &mut Reader<'a>) -> Result<Self>

Reads the record from its payload.

Errors

Returns Error::UnsupportedVersion if the layout version is not one this build knows, Error::Truncated if the payload ends early, or Error::NotUtf8 if the decoder name is not text.
