Trait FromWordPointer

pub trait FromWordPointer<'a>: Sized + 'a {
    type Err: Display;

    // Required method
    fn from_cstr(s: &'a CStr) -> Result<Self, Self::Err>;
}

Parse a value from a CStr instance.

Required Associated Types

type Err: Display

The type returned in the event of a conversion error.

Required Methods

fn from_cstr(s: &'a CStr) -> Result<Self, Self::Err>

Parse the value in s to return a value of this type.

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.
