Trait OctetsFrom

pub trait OctetsFrom<Source>: Sized {
    type Error: Into<ShortBuf>;

    // Required method
    fn try_octets_from(source: Source) -> Result<Self, Self::Error>;

    // Provided method
    fn octets_from(source: Source) -> Self
       where Self::Error: Into<Infallible> { ... }
}

Convert a type from one octets type to another.

This trait allows creating a value of a type that is generic over an octets sequence from an identical value using a different type of octets sequence.

This is different from just From in that the conversion may fail if the source sequence is longer than the space available for the target type.

Required Associated Types

type Error: Into<ShortBuf>

Required Methods

fn try_octets_from(source: Source) -> Result<Self, Self::Error>

Performs the conversion.

Provided Methods

fn octets_from(source: Source) -> Self

where Self::Error: Into<Infallible>,

Performs an infallible conversion.

Object Safety

This trait is not object safe.
