Trait FromFrame 

pub trait FromFrame: Sized {
    type Error;

    // Required method
    fn parse_frame(frame: &mut Bytes) -> Result<Self, Self::Error>;

    // Provided method
    fn from_frame(frame: Bytes) -> Result<Self, Self::Error> { ... }
}

Trait for converting a frame into `Self.

Required Associated Types

type Error

The error type returned when parsing a frame.

Required Methods

fn parse_frame(frame: &mut Bytes) -> Result<Self, Self::Error>

Parse a frame into a Self.

Provided Methods

fn from_frame(frame: Bytes) -> Result<Self, Self::Error>

Convert a frame into a Self.

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.
