Trait FromStr

pub trait FromStr: Sized {
    type Error: Error + Send + Sync + 'static;

    // Required method
    fn from_str(s: &str) -> Result<Self, Self::Error>;
}

Defines the way to parse the object from a UTF-8 string.

This is like the standard FromStr trait, except that it imposes additional bounds on the error type to make it more usable for aggregation to higher level errors and passing between threads.

Required Associated Types

type Error: Error + Send + Sync + 'static

Required Methods

fn from_str(s: &str) -> Result<Self, Self::Error>

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.
