}Expand description
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 Methods§
Sourcefn try_octets_from(source: Source) -> Result<Self, Self::Error>
fn try_octets_from(source: Source) -> Result<Self, Self::Error>
Performs the conversion.
Provided Methods§
Sourcefn octets_from(source: Source) -> Self
fn octets_from(source: Source) -> Self
Performs an infallible conversion.
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.
