Trait bytecodec::ExactBytesEncode
[−]
[src]
pub trait ExactBytesEncode: Encode { fn requiring_bytes(&self) -> u64 { ... } }
This trait indicates that the encoder always known the exact bytes required to encode remaining items.
By implementing this trait, the user of those encoders can implement length-prefixed protocols easily.
Provided Methods
fn requiring_bytes(&self) -> u64
Returns the number of bytes required to encode all the items in the encoder.
