Trait Parse

pub trait Parse<PS: ParseStrategy>: Sized {
    type Error: Into<Error>;

    // Required method
    fn parse(bytes: PS) -> Result<(Self, PS), Self::Error>;
}

A data structure that can be parsed as a part of a binary policy.

Required Associated Types

type Error: Into<Error>

The type of error that may be returned from parse(), usually ParseError or anyhow::Error.

Required Methods

fn parse(bytes: PS) -> Result<(Self, PS), Self::Error>

Parses a Self from bytes, returning the Self and trailing bytes, or an error if bytes corresponding to a Self are malformed.

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.
